Given numbers are 751,478,284,784

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

The LCM of 751,478,284,784 is 9991075696.

Find LCM of 751,478,284,784 with Prime Factorization

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

2 x 2 x 751 x 239 x 71 x 196 = 9991075696

Therefore, the lowest common multiple of 751,478,284,784 is 9991075696.

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.

751 x 478 x 284 x 784 = 79928605568

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.

751 : 1, 751

478 : 1, 2, 239, 478

284 : 1, 2, 4, 71, 142, 284

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 751,478,284,784, is 1.

Now, the common factors can be found like this.

751:751

478:2x 239

284:2x 2x 71

784:2x 2x 2x 2x 7x 7

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 2 = 8

Therefore, the value for common factors is 8.

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 = 79928605568/(1x8)

LCM = 79928605568/8

LCM = 9991075696

Thus, we can understand that the LCM of 751,478,284,784 is 9991075696.
