Given numbers are 728,637,226,540

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

The LCM of 728,637,226,540 is 77739480.

Find LCM of 728,637,226,540 with Prime Factorization

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

2 x 2 x 7 x 13 x 2 x 7 x 113 x 135 = 77739480

Therefore, the lowest common multiple of 728,637,226,540 is 77739480.

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.

728 x 637 x 226 x 540 = 56594341440

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.

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

637 : 1, 7, 13, 49, 91, 637

226 : 1, 2, 113, 226

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,637,226,540, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

637:7x 7x 13

226:2x 113

540:2x 2x 3x 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 2x 2x 7x 13 = 728

Therefore, the value for common factors is 728.

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 = 56594341440/(1x728)

LCM = 56594341440/728

LCM = 77739480

Thus, we can understand that the LCM of 728,637,226,540 is 77739480.
