Calculate the LCM of 639,537,426,664

Given numbers are 639,537,426,664

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

The LCM of 639,537,426,664 is 75948984.

Find LCM of 639,537,426,664 with Prime Factorization


2 639, 537, 426, 664
3 639, 537, 213, 332
71 71, 179, 213, 332
1, 179, 3, 332

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

2 x 3 x 71 x 1 x 179 x 3 x 332 = 75948984

Therefore, the lowest common multiple of 639,537,426,664 is 75948984.

LCM Formula to Find Lowest Common Multiple of 639,537,426,664

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.

639 x 537 x 426 x 664 = 97062801552

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.

639 : 1, 3, 9, 71, 213, 639

537 : 1, 3, 179, 537

426 : 1, 2, 3, 6, 71, 142, 213, 426

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,537,426,664, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

537:3x 179

426:2x 3x 71

664:2x 2x 2x 83

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

2x 3x 3x 71 = 1278

Therefore, the value for common factors is 1278.

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 = 97062801552/(1x1278)

LCM = 97062801552/1278

LCM = 75948984

Thus, we can understand that the LCM of 639,537,426,664 is 75948984.
