Find LCM of 408,663,442,979 with Prime Factorization


2 408, 663, 442, 979
3 204, 663, 221, 979
13 68, 221, 221, 979
17 68, 17, 17, 979
4, 1, 1, 979

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

2 x 3 x 13 x 17 x 4 x 1 x 1 x 979 = 5192616

Therefore, the lowest common multiple of 408,663,442,979 is 5192616.

LCM Formula to Find Lowest Common Multiple of 408,663,442,979

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.

408 x 663 x 442 x 979 = 117051949872

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.

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

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

442 : 1, 2, 13, 17, 26, 34, 221, 442

979 : 1, 11, 89, 979

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,663,442,979, is 1.

Now, the common factors can be found like this.

408:2x 2x 2x 3x 17

663:3x 13x 17

442:2x 13x 17

979:11x 89

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 13x 17x 17 = 22542

Therefore, the value for common factors is 22542.

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 = 117051949872/(1x22542)

LCM = 117051949872/22542

LCM = 5192616

Thus, we can understand that the LCM of 408,663,442,979 is 5192616.
