Calculate the LCM of 422,308,729,641

Given numbers are 422,308,729,641

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

The LCM of 422,308,729,641 is 30368177532.

Find LCM of 422,308,729,641 with Prime Factorization


2 422, 308, 729, 641
211, 154, 729, 641

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

2 x 211 x 154 x 729 x 641 = 30368177532

Therefore, the lowest common multiple of 422,308,729,641 is 30368177532.

LCM Formula to Find Lowest Common Multiple of 422,308,729,641

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 308 x 729 x 641 = 60736355064

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

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

729 : 1, 3, 9, 27, 81, 243, 729

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,308,729,641, is 1.

Now, the common factors can be found like this.

422:2x 211

308:2x 2x 7x 11

729:3x 3x 3x 3x 3x 3

641:641

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 = 60736355064/(1x2)

LCM = 60736355064/2

LCM = 30368177532

Thus, we can understand that the LCM of 422,308,729,641 is 30368177532.
