What is the lcm of 8 and 10?

The least common multiple of 8 and 10 is 40.

To find the least common multiple (LCM) of two numbers, start by listing the multiples of each number. The multiples of 8 are 8, 16, 24, 32, and 40. The multiples of 10 are 10, 20, 30, and 40. The LCM of 8 and 10 is the smallest number that appears on both lists of multiples, which is 40.

It's also possible to find the LCM using the greatest common divisor (GCD). To find the GCD of two numbers, list the factors of each number. The factors of 8 are 1, 2, 4, and 8. The factors of 10 are 1, 2, 5, and 10. The largest number that appears on both lists of factors is 5. Therefore, the GCD of 8 and 10 is 5.

To find the LCM using the GCD, divide the product of the two numbers by the GCD. In this case, the LCM of 8 and 10 is (8 x 10) / 5, which is equal to 40.

There is no one definitive answer to this question - it depends on what methods you are familiar with and feel comfortable using. However, one way to find the lowest common multiple (LCM) of two numbers is by using the following formula:

LCM(a,b) = |a*b|/GCD(a,b)

where GCD is the greatest common divisor.

To use this formula to find the LCM of 8 and 10, we first need to calculate the GCD. One way to do this is using the Euclidean algorithm, which can be summarized as follows:

1) Divide the larger number by the smaller number. In our case, this would be 8/10. The remainder is the new smaller number - in this instance, 2. 2) Divide the new smaller number by the remainder from the previous step. In our case, this would be 10/2. The remainder is 0, which means that 2 is the GCD.

Now that we have the GCD, we can plugged it into the LCM formula to get:

LCM(8,10) = |8*10|/2 = 80/2 = 40

So, the LCM of 8 and 10 is 40.

The lowest common multiple (LCM) of two integers is the smallest positive integer that is a multiple of both integers. To find the LCM of 8 and 10 using the prime factorization method, we need to find the prime factorization of each integer.

The prime factorization of 8 is 2 x 2 x 2, and the prime factorization of 10 is 2 x 5. To find the LCM of 8 and 10, we need to find the product of the prime factors of each integer that are shared by both integers. In this case, the only shared prime factor is 2. Therefore, the LCM of 8 and 10 is 2 x 2 x 2 x 5, or 40.

In mathematics, the least common multiple, or lowest common denominator (LCD), of two integers a and b, usually denoted by LCM(a, b), is the smallest positive integer that is divisible by both a and b.

The Euclidean algorithm is a method for efficiently finding the greatest common divisor (GCD) of two numbers, the largest number that divides both of them without leaving a remainder. It is named after the Greek mathematician Euclid, who first described it in his Elements (c. 300 BC). It is an efficient method for reducing large numbers to their greatest common factor, and is still in use today.

The algorithm is based on the observation that the GCD of two numbers also divides their difference. Thus, if a and b are two numbers with a > b, then GCD(a, b) = GCD(a-b, b). By repeatedly applying this observation, the Euclidean algorithm reduces the problem of finding the GCD of two numbers to the problem of finding the GCD of two smaller numbers. The approach is continued until the two numbers are equal, at which point the current GCD is returned.

The Euclidean algorithm is also significant because it is an example of an algorithm that is guaranteed to terminate. That is, given any two positive integers, the algorithm will always produce a result in a finite number of steps. This is not the case for all algorithms; for example, the naive algorithm for finding the GCD of two numbers, which consists of repeatedly subtracting the smaller number from the larger number until they are equal, does not always terminate.

The LCD of 8 and 10 can be found using the Euclidean algorithm as follows:

First, we determine the GCD of 8 and 10 using the Euclidean algorithm.

8 = 10 - 2 10 = 8 + 2

So, GCD(8, 10) = GCD(10, 8) = 2.

Now, we can use the fact that LCM(a, b) = (a*b)/GCD(a, b) to compute the LCM of 8 and 10:

LCM(8, 10) = (8 * 10) / GCD(8, 10) LCM(8, 10) = (8 * 10) / 2 LCM(8,
