Given numbers are 977,872,172,855

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 977,872,172,855 is 31321721160.

Find LCM of 977,872,172,855 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 977 x 218 x 43 x 855 = 31321721160

Therefore, the lowest common multiple of 977,872,172,855 is 31321721160.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

977 x 872 x 172 x 855 = 125286884640

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

977 : 1, 977

872 : 1, 2, 4, 8, 109, 218, 436, 872

172 : 1, 2, 4, 43, 86, 172

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 977,872,172,855, is 1.

Now, the common factors can be found like this.

977:977

872:2x 2x 2x 109

172:2x 2x 43

855:3x 3x 5x 19

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2 = 4

Therefore, the value for common factors is 4.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 125286884640/(1x4)

LCM = 125286884640/4

LCM = 31321721160

Thus, we can understand that the LCM of 977,872,172,855 is 31321721160.
