Given numbers are 129,731,637,971

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

The LCM of 129,731,637,971 is 1356429711.

Find LCM of 129,731,637,971 with Prime Factorization

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

43 x 3 x 17 x 637 x 971 = 1356429711

Therefore, the lowest common multiple of 129,731,637,971 is 1356429711.

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.

129 x 731 x 637 x 971 = 58326477573

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.

129 : 1, 3, 43, 129

731 : 1, 17, 43, 731

637 : 1, 7, 13, 49, 91, 637

971 : 1, 971

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 129,731,637,971, is 1.

Now, the common factors can be found like this.

129:3x 43

731:17x 43

637:7x 7x 13

971:971

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

43 = 43

Therefore, the value for common factors is 43.

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 = 58326477573/(1x43)

LCM = 58326477573/43

LCM = 1356429711

Thus, we can understand that the LCM of 129,731,637,971 is 1356429711.
