Given numbers are 428,779,473,920

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

The LCM of 428,779,473,920 is 36271891480.

Find LCM of 428,779,473,920 with Prime Factorization

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

2 x 2 x 107 x 779 x 473 x 230 = 36271891480

Therefore, the lowest common multiple of 428,779,473,920 is 36271891480.

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.

428 x 779 x 473 x 920 = 145087565920

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.

428 : 1, 2, 4, 107, 214, 428

779 : 1, 19, 41, 779

473 : 1, 11, 43, 473

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,779,473,920, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

779:19x 41

473:11x 43

920:2x 2x 2x 5x 23

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 145087565920/(1x4)

LCM = 145087565920/4

LCM = 36271891480

Thus, we can understand that the LCM of 428,779,473,920 is 36271891480.
