Given numbers are 126,920,891,318,728

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

The LCM of 126,920,891,318,728 is 3953509560.

Find LCM of 126,920,891,318,728 with Prime Factorization

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

2 x 2 x 2 x 3 x 3 x 7 x 1 x 115 x 99 x 53 x 13 = 3953509560

Therefore, the lowest common multiple of 126,920,891,318,728 is 3953509560.

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.

126 x 920 x 891 x 318 x 728 = 23910825818880

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.

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

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

891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891

318 : 1, 2, 3, 6, 53, 106, 159, 318

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,920,891,318,728, is 1.

Now, the common factors can be found like this.

126:2x 3x 3x 7

920:2x 2x 2x 5x 23

891:3x 3x 3x 3x 11

318:2x 3x 53

728:2x 2x 2x 7x 13

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 2x 2x 3x 3x 3x 7 = 6048

Therefore, the value for common factors is 6048.

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 = 23910825818880/(1x6048)

LCM = 23910825818880/6048

LCM = 3953509560

Thus, we can understand that the LCM of 126,920,891,318,728 is 3953509560.
