Given numbers are 647,686,613,957,720

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

The LCM of 647,686,613,957,720 is 31245109766640.

Find LCM of 647,686,613,957,720 with Prime Factorization

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

2 x 3 x 647 x 343 x 613 x 319 x 120 = 31245109766640

Therefore, the lowest common multiple of 647,686,613,957,720 is 31245109766640.

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.

647 x 686 x 613 x 957 x 720 = 187470658599840

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.

647 : 1, 647

686 : 1, 2, 7, 14, 49, 98, 343, 686

613 : 1, 613

957 : 1, 3, 11, 29, 33, 87, 319, 957

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 647,686,613,957,720, is 1.

Now, the common factors can be found like this.

647:647

686:2x 7x 7x 7

613:613

957:3x 11x 29

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 3 = 6

Therefore, the value for common factors is 6.

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 = 187470658599840/(1x6)

LCM = 187470658599840/6

LCM = 31245109766640

Thus, we can understand that the LCM of 647,686,613,957,720 is 31245109766640.
