Calculate the LCM of 556,640,130,637

Given numbers are 556,640,130,637

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

The LCM of 556,640,130,637 is 56667520.

Find LCM of 556,640,130,637 with Prime Factorization


2 556, 640, 130, 637
2 278, 320, 65, 637
5 139, 160, 65, 637
13 139, 32, 13, 637
139, 32, 1, 49

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

2 x 2 x 5 x 13 x 139 x 32 x 1 x 49 = 56667520

Therefore, the lowest common multiple of 556,640,130,637 is 56667520.

LCM Formula to Find Lowest Common Multiple of 556,640,130,637

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.

556 x 640 x 130 x 637 = 29467110400

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.

556 : 1, 2, 4, 139, 278, 556

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

130 : 1, 2, 5, 10, 13, 26, 65, 130

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,640,130,637, is 1.

Now, the common factors can be found like this.

556:2x 2x 139

640:2x 2x 2x 2x 2x 2x 2x 5

130:2x 5x 13

637:7x 7x 13

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

2x 2x 2x 5x 13 = 520

Therefore, the value for common factors is 520.

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 = 29467110400/(1x520)

LCM = 29467110400/520

LCM = 56667520

Thus, we can understand that the LCM of 556,640,130,637 is 56667520.
