Calculate the LCM of 352,638,691,435

Given numbers are 352,638,691,435

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

The LCM of 352,638,691,435 is 105805920.

Find LCM of 352,638,691,435 with Prime Factorization


2 352, 638, 691, 435
11 176, 319, 691, 435
29 16, 29, 691, 435
16, 1, 691, 15

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

2 x 11 x 29 x 16 x 1 x 691 x 15 = 105805920

Therefore, the lowest common multiple of 352,638,691,435 is 105805920.

LCM Formula to Find Lowest Common Multiple of 352,638,691,435

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.

352 x 638 x 691 x 435 = 67504176960

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.

352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352

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

691 : 1, 691

435 : 1, 3, 5, 15, 29, 87, 145, 435

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 352,638,691,435, is 1.

Now, the common factors can be found like this.

352:2x 2x 2x 2x 2x 11

638:2x 11x 29

691:691

435:3x 5x 29

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

2x 11x 29 = 638

Therefore, the value for common factors is 638.

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 = 67504176960/(1x638)

LCM = 67504176960/638

LCM = 105805920

Thus, we can understand that the LCM of 352,638,691,435 is 105805920.
