Calculate the LCM of 872,340,979,489,778

Given numbers are 872,340,979,489,778

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

The LCM of 872,340,979,489,778 is 13803097729080.

Find LCM of 872,340,979,489,778 with Prime Factorization


2 872, 340, 979, 489, 778
2 436, 170, 979, 489, 389
218, 85, 979, 489, 389

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

2 x 2 x 218 x 85 x 979 x 489 x 389 = 13803097729080

Therefore, the lowest common multiple of 872,340,979,489,778 is 13803097729080.

LCM Formula to Find Lowest Common Multiple of 872,340,979,489,778

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.

872 x 340 x 979 x 489 x 778 = 110424781832640

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.

872 : 1, 2, 4, 8, 109, 218, 436, 872

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

979 : 1, 11, 89, 979

489 : 1, 3, 163, 489

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,340,979,489,778, is 1.

Now, the common factors can be found like this.

872:2x 2x 2x 109

340:2x 2x 5x 17

979:11x 89

489:3x 163

778:2x 389

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 110424781832640/(1x8)

LCM = 110424781832640/8

LCM = 13803097729080

Thus, we can understand that the LCM of 872,340,979,489,778 is 13803097729080.
