Calculate the LCM of 646,656,758,543

Given numbers are 646,656,758,543

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

The LCM of 646,656,758,543 is 43605914736.

Find LCM of 646,656,758,543 with Prime Factorization


2 646, 656, 758, 543
323, 328, 379, 543

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

2 x 323 x 328 x 379 x 543 = 43605914736

Therefore, the lowest common multiple of 646,656,758,543 is 43605914736.

LCM Formula to Find Lowest Common Multiple of 646,656,758,543

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 656 x 758 x 543 = 174423658944

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

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

758 : 1, 2, 379, 758

543 : 1, 3, 181, 543

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,656,758,543, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

656:2x 2x 2x 2x 41

758:2x 379

543:3x 181

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 = 174423658944/(1x4)

LCM = 174423658944/4

LCM = 43605914736

Thus, we can understand that the LCM of 646,656,758,543 is 43605914736.
