Given numbers are 479,456,560,638

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

The LCM of 479,456,560,638 is 4877407920.

Find LCM of 479,456,560,638 with Prime Factorization

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

2 x 2 x 2 x 479 x 57 x 70 x 319 = 4877407920

Therefore, the lowest common multiple of 479,456,560,638 is 4877407920.

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.

479 x 456 x 560 x 638 = 78038526720

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.

479 : 1, 479

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 479,456,560,638, is 1.

Now, the common factors can be found like this.

479:479

456:2x 2x 2x 3x 19

560:2x 2x 2x 2x 5x 7

638:2x 11x 29

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 78038526720/(1x16)

LCM = 78038526720/16

LCM = 4877407920

Thus, we can understand that the LCM of 479,456,560,638 is 4877407920.
