Calculate the LCM of 997,664,209,436

Given numbers are 997,664,209,436

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

The LCM of 997,664,209,436 is 15081204248.

Find LCM of 997,664,209,436 with Prime Factorization


2 997, 664, 209, 436
2 997, 332, 209, 218
997, 166, 209, 109

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

2 x 2 x 997 x 166 x 209 x 109 = 15081204248

Therefore, the lowest common multiple of 997,664,209,436 is 15081204248.

LCM Formula to Find Lowest Common Multiple of 997,664,209,436

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 664 x 209 x 436 = 60324816992

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

664 : 1, 2, 4, 8, 83, 166, 332, 664

209 : 1, 11, 19, 209

436 : 1, 2, 4, 109, 218, 436

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,664,209,436, is 1.

Now, the common factors can be found like this.

997:997

664:2x 2x 2x 83

209:11x 19

436:2x 2x 109

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 = 60324816992/(1x4)

LCM = 60324816992/4

LCM = 15081204248

Thus, we can understand that the LCM of 997,664,209,436 is 15081204248.
