Given numbers are 671,170,129,872

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

The LCM of 671,170,129,872 is 6415753080.

Find LCM of 671,170,129,872 with Prime Factorization

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

2 x 671 x 85 x 129 x 436 = 6415753080

Therefore, the lowest common multiple of 671,170,129,872 is 6415753080.

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.

671 x 170 x 129 x 872 = 12831506160

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.

671 : 1, 11, 61, 671

170 : 1, 2, 5, 10, 17, 34, 85, 170

129 : 1, 3, 43, 129

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,170,129,872, is 1.

Now, the common factors can be found like this.

671:11x 61

170:2x 5x 17

129:3x 43

872:2x 2x 2x 109

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

2 = 2

Therefore, the value for common factors is 2.

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 = 12831506160/(1x2)

LCM = 12831506160/2

LCM = 6415753080

Thus, we can understand that the LCM of 671,170,129,872 is 6415753080.
