The LCM of 847,494,721,776 is 16721656952.

Find LCM of 847,494,721,776 with Prime Factorization


2 847, 494, 721, 776
7 847, 247, 721, 388
121, 247, 103, 388

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

2 x 7 x 121 x 247 x 103 x 388 = 16721656952

Therefore, the lowest common multiple of 847,494,721,776 is 16721656952.

LCM Formula to Find Lowest Common Multiple of 847,494,721,776

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.

847 x 494 x 721 x 776 = 234103197328

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.

847 : 1, 7, 11, 77, 121, 847

494 : 1, 2, 13, 19, 26, 38, 247, 494

721 : 1, 7, 103, 721

776 : 1, 2, 4, 8, 97, 194, 388, 776

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,494,721,776, is 1.

Now, the common factors can be found like this.

847:7x 11x 11

494:2x 13x 19

721:7x 103

776:2x 2x 2x 97

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 234103197328/(1x14)

LCM = 234103197328/14

LCM = 16721656952

Thus, we can understand that the LCM of 847,494,721,776 is 16721656952.
