Calculate the LCM of 646,547,864,706

Given numbers are 646,547,864,706

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

The LCM of 646,547,864,706 is 53886291552.

Find LCM of 646,547,864,706 with Prime Factorization


2 646, 547, 864, 706
323, 547, 432, 353

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

2 x 323 x 547 x 432 x 353 = 53886291552

Therefore, the lowest common multiple of 646,547,864,706 is 53886291552.

LCM Formula to Find Lowest Common Multiple of 646,547,864,706

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.

646 x 547 x 864 x 706 = 215545166208

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

547 : 1, 547

864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864

706 : 1, 2, 353, 706

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,547,864,706, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

547:547

864:2x 2x 2x 2x 2x 3x 3x 3

706:2x 353

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 = 215545166208/(1x4)

LCM = 215545166208/4

LCM = 53886291552

Thus, we can understand that the LCM of 646,547,864,706 is 53886291552.
