Given numbers are 721,198,916,671

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

The LCM of 721,198,916,671 is 3988373004.

Find LCM of 721,198,916,671 with Prime Factorization

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

2 x 11 x 721 x 9 x 458 x 61 = 3988373004

Therefore, the lowest common multiple of 721,198,916,671 is 3988373004.

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.

721 x 198 x 916 x 671 = 87744206088

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.

721 : 1, 7, 103, 721

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

916 : 1, 2, 4, 229, 458, 916

671 : 1, 11, 61, 671

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,198,916,671, is 1.

Now, the common factors can be found like this.

721:7x 103

198:2x 3x 3x 11

916:2x 2x 229

671:11x 61

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 87744206088/(1x22)

LCM = 87744206088/22

LCM = 3988373004

Thus, we can understand that the LCM of 721,198,916,671 is 3988373004.
