Calculate the LCM of 922,171,491,813

Given numbers are 922,171,491,813

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

The LCM of 922,171,491,813 is 20978663382.

Find LCM of 922,171,491,813 with Prime Factorization


3 922, 171, 491, 813
922, 57, 491, 271

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

3 x 922 x 57 x 491 x 271 = 20978663382

Therefore, the lowest common multiple of 922,171,491,813 is 20978663382.

LCM Formula to Find Lowest Common Multiple of 922,171,491,813

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.

922 x 171 x 491 x 813 = 62935990146

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.

922 : 1, 2, 461, 922

171 : 1, 3, 9, 19, 57, 171

491 : 1, 491

813 : 1, 3, 271, 813

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 922,171,491,813, is 1.

Now, the common factors can be found like this.

922:2x 461

171:3x 3x 19

491:491

813:3x 271

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

3 = 3

Therefore, the value for common factors is 3.

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 = 62935990146/(1x3)

LCM = 62935990146/3

LCM = 20978663382

Thus, we can understand that the LCM of 922,171,491,813 is 20978663382.
