Given numbers are 971,642,644,479

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

The LCM of 971,642,644,479 is 96149192916.

Find LCM of 971,642,644,479 with Prime Factorization

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

2 x 971 x 321 x 322 x 479 = 96149192916

Therefore, the lowest common multiple of 971,642,644,479 is 96149192916.

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.

971 x 642 x 644 x 479 = 192298385832

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.

971 : 1, 971

642 : 1, 2, 3, 6, 107, 214, 321, 642

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

479 : 1, 479

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,642,644,479, is 1.

Now, the common factors can be found like this.

971:971

642:2x 3x 107

644:2x 2x 7x 23

479:479

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 = 192298385832/(1x2)

LCM = 192298385832/2

LCM = 96149192916

Thus, we can understand that the LCM of 971,642,644,479 is 96149192916.
