Given numbers are 997,614,638,668

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

The LCM of 997,614,638,668 is 65222986268.

Find LCM of 997,614,638,668 with Prime Factorization

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

2 x 997 x 307 x 319 x 334 = 65222986268

Therefore, the lowest common multiple of 997,614,638,668 is 65222986268.

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.

997 x 614 x 638 x 668 = 260891945072

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.

997 : 1, 997

614 : 1, 2, 307, 614

638 : 1, 2, 11, 22, 29, 58, 319, 638

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,614,638,668, is 1.

Now, the common factors can be found like this.

997:997

614:2x 307

638:2x 11x 29

668:2x 2x 167

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 = 260891945072/(1x4)

LCM = 260891945072/4

LCM = 65222986268

Thus, we can understand that the LCM of 997,614,638,668 is 65222986268.
