Given numbers are 721,138,859,328

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

The LCM of 721,138,859,328 is 14016880248.

Find LCM of 721,138,859,328 with Prime Factorization

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

2 x 721 x 69 x 859 x 164 = 14016880248

Therefore, the lowest common multiple of 721,138,859,328 is 14016880248.

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 138 x 859 x 328 = 28033760496

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

859 : 1, 859

328 : 1, 2, 4, 8, 41, 82, 164, 328

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,138,859,328, is 1.

Now, the common factors can be found like this.

721:7x 103

138:2x 3x 23

859:859

328:2x 2x 2x 41

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

2 = 2

Therefore, the value for common factors is 2.

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 = 28033760496/(1x2)

LCM = 28033760496/2

LCM = 14016880248

Thus, we can understand that the LCM of 721,138,859,328 is 14016880248.
