Given numbers are 671,142,854,906

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

The LCM of 671,142,854,906 is 302139222.

Find LCM of 671,142,854,906 with Prime Factorization

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

2 x 61 x 11 x 71 x 7 x 453 = 302139222

Therefore, the lowest common multiple of 671,142,854,906 is 302139222.

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 142 x 854 x 906 = 73721970168

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

142 : 1, 2, 71, 142

854 : 1, 2, 7, 14, 61, 122, 427, 854

906 : 1, 2, 3, 6, 151, 302, 453, 906

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,142,854,906, is 1.

Now, the common factors can be found like this.

671:11x 61

142:2x 71

854:2x 7x 61

906:2x 3x 151

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

2x 2x 61 = 244

Therefore, the value for common factors is 244.

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 = 73721970168/(1x244)

LCM = 73721970168/244

LCM = 302139222

Thus, we can understand that the LCM of 671,142,854,906 is 302139222.
