Given numbers are 617,971,668,920

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

The LCM of 617,971,668,920 is 92046799480.

Find LCM of 617,971,668,920 with Prime Factorization

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

2 x 2 x 617 x 971 x 167 x 230 = 92046799480

Therefore, the lowest common multiple of 617,971,668,920 is 92046799480.

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.

617 x 971 x 668 x 920 = 368187197920

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.

617 : 1, 617

971 : 1, 971

668 : 1, 2, 4, 167, 334, 668

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 617,971,668,920, is 1.

Now, the common factors can be found like this.

617:617

971:971

668:2x 2x 167

920:2x 2x 2x 5x 23

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 368187197920/(1x4)

LCM = 368187197920/4

LCM = 92046799480

Thus, we can understand that the LCM of 617,971,668,920 is 92046799480.
