Given numbers are 517,646,779,720

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

The LCM of 517,646,779,720 is 4929574320.

Find LCM of 517,646,779,720 with Prime Factorization

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

2 x 19 x 517 x 17 x 41 x 360 = 4929574320

Therefore, the lowest common multiple of 517,646,779,720 is 4929574320.

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.

517 x 646 x 779 x 720 = 187323824160

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.

517 : 1, 11, 47, 517

646 : 1, 2, 17, 19, 34, 38, 323, 646

779 : 1, 19, 41, 779

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,646,779,720, is 1.

Now, the common factors can be found like this.

517:11x 47

646:2x 17x 19

779:19x 41

720:2x 2x 2x 2x 3x 3x 5

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

2x 19 = 38

Therefore, the value for common factors is 38.

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 = 187323824160/(1x38)

LCM = 187323824160/38

LCM = 4929574320

Thus, we can understand that the LCM of 517,646,779,720 is 4929574320.
