Calculate the LCM of 3,641,641,422

Given numbers are 3,641,641,422

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

The LCM of 3,641,641,422 is 811506.

Find LCM of 3,641,641,422 with Prime Factorization


641 3, 641, 641, 422
3, 1, 1, 422

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

641 x 3 x 1 x 1 x 422 = 811506

Therefore, the lowest common multiple of 3,641,641,422 is 811506.

LCM Formula to Find Lowest Common Multiple of 3,641,641,422

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.

3 x 641 x 641 x 422 = 520175346

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.

3 : 1, 3

641 : 1, 641

641 : 1, 641

422 : 1, 2, 211, 422

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 3,641,641,422, is 1.

Now, the common factors can be found like this.

3:3

641:641

641:641

422:2x 211

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

641 = 641

Therefore, the value for common factors is 641.

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 = 520175346/(1x641)

LCM = 520175346/641

LCM = 811506

Thus, we can understand that the LCM of 3,641,641,422 is 811506.
