The LCM of 413,693,418,856 is 664986168.

Find LCM of 413,693,418,856 with Prime Factorization


2 413, 693, 418, 856
7 413, 693, 209, 428
11 59, 99, 209, 428
59, 9, 19, 428

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

2 x 7 x 11 x 59 x 9 x 19 x 428 = 664986168

Therefore, the lowest common multiple of 413,693,418,856 is 664986168.

LCM Formula to Find Lowest Common Multiple of 413,693,418,856

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.

413 x 693 x 418 x 856 = 102407869872

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.

413 : 1, 7, 59, 413

693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693

418 : 1, 2, 11, 19, 22, 38, 209, 418

856 : 1, 2, 4, 8, 107, 214, 428, 856

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 413,693,418,856, is 1.

Now, the common factors can be found like this.

413:7x 59

693:3x 3x 7x 11

418:2x 11x 19

856:2x 2x 2x 107

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

2x 7x 11 = 154

Therefore, the value for common factors is 154.

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 = 102407869872/(1x154)

LCM = 102407869872/154

LCM = 664986168

Thus, we can understand that the LCM of 413,693,418,856 is 664986168.
