Calculate the LCM of 779,298,420,806

Given numbers are 779,298,420,806

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

The LCM of 779,298,420,806 is 19646177460.

Find LCM of 779,298,420,806 with Prime Factorization


2 779, 298, 420, 806
779, 149, 210, 403

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

2 x 779 x 149 x 210 x 403 = 19646177460

Therefore, the lowest common multiple of 779,298,420,806 is 19646177460.

LCM Formula to Find Lowest Common Multiple of 779,298,420,806

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.

779 x 298 x 420 x 806 = 78584709840

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.

779 : 1, 19, 41, 779

298 : 1, 2, 149, 298

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

806 : 1, 2, 13, 26, 31, 62, 403, 806

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,298,420,806, is 1.

Now, the common factors can be found like this.

779:19x 41

298:2x 149

420:2x 2x 3x 5x 7

806:2x 13x 31

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 78584709840/(1x4)

LCM = 78584709840/4

LCM = 19646177460

Thus, we can understand that the LCM of 779,298,420,806 is 19646177460.
