Calculate the LCM of 637,724,605,681,326

Given numbers are 637,724,605,681,326

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

The LCM of 637,724,605,681,326 is 30971917196220.

Find LCM of 637,724,605,681,326 with Prime Factorization


2 637, 724, 605, 681, 326
637, 362, 605, 681, 163

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

2 x 637 x 362 x 605 x 681 x 163 = 30971917196220

Therefore, the lowest common multiple of 637,724,605,681,326 is 30971917196220.

LCM Formula to Find Lowest Common Multiple of 637,724,605,681,326

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.

637 x 724 x 605 x 681 x 326 = 61943834392440

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.

637 : 1, 7, 13, 49, 91, 637

724 : 1, 2, 4, 181, 362, 724

605 : 1, 5, 11, 55, 121, 605

681 : 1, 3, 227, 681

326 : 1, 2, 163, 326

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,724,605,681,326, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

724:2x 2x 181

605:5x 11x 11

681:3x 227

326:2x 163

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 = 61943834392440/(1x2)

LCM = 61943834392440/2

LCM = 30971917196220

Thus, we can understand that the LCM of 637,724,605,681,326 is 30971917196220.
