Calculate the LCM of 422,643,941,790

Given numbers are 422,643,941,790

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

The LCM of 422,643,941,790 is 100857951470.

Find LCM of 422,643,941,790 with Prime Factorization


2 422, 643, 941, 790
211, 643, 941, 395

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

2 x 211 x 643 x 941 x 395 = 100857951470

Therefore, the lowest common multiple of 422,643,941,790 is 100857951470.

LCM Formula to Find Lowest Common Multiple of 422,643,941,790

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.

422 x 643 x 941 x 790 = 201715902940

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.

422 : 1, 2, 211, 422

643 : 1, 643

941 : 1, 941

790 : 1, 2, 5, 10, 79, 158, 395, 790

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,643,941,790, is 1.

Now, the common factors can be found like this.

422:2x 211

643:643

941:941

790:2x 5x 79

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

2 = 2

Therefore, the value for common factors is 2.

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 = 201715902940/(1x2)

LCM = 201715902940/2

LCM = 100857951470

Thus, we can understand that the LCM of 422,643,941,790 is 100857951470.
