Find LCM of 826,429,663,636 with Prime Factorization


2 826, 429, 663, 636
3 413, 429, 663, 318
13 413, 143, 221, 106
413, 11, 17, 106

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

2 x 3 x 13 x 413 x 11 x 17 x 106 = 638545908

Therefore, the lowest common multiple of 826,429,663,636 is 638545908.

LCM Formula to Find Lowest Common Multiple of 826,429,663,636

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.

826 x 429 x 663 x 636 = 149419742472

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.

826 : 1, 2, 7, 14, 59, 118, 413, 826

429 : 1, 3, 11, 13, 33, 39, 143, 429

663 : 1, 3, 13, 17, 39, 51, 221, 663

636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 826,429,663,636, is 1.

Now, the common factors can be found like this.

826:2x 7x 59

429:3x 11x 13

663:3x 13x 17

636:2x 2x 3x 53

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 13 = 234

Therefore, the value for common factors is 234.

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 = 149419742472/(1x234)

LCM = 149419742472/234

LCM = 638545908

Thus, we can understand that the LCM of 826,429,663,636 is 638545908.
