Calculate the LCM of 724,256,722,642

Given numbers are 724,256,722,642

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

The LCM of 724,256,722,642 is 5369462016.

Find LCM of 724,256,722,642 with Prime Factorization


2 724, 256, 722, 642
2 362, 128, 361, 321
181, 64, 361, 321

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

2 x 2 x 181 x 64 x 361 x 321 = 5369462016

Therefore, the lowest common multiple of 724,256,722,642 is 5369462016.

LCM Formula to Find Lowest Common Multiple of 724,256,722,642

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.

724 x 256 x 722 x 642 = 85911392256

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.

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

256 : 1, 2, 4, 8, 16, 32, 64, 128, 256

722 : 1, 2, 19, 38, 361, 722

642 : 1, 2, 3, 6, 107, 214, 321, 642

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,256,722,642, is 2.

Now, the common factors can be found like this.

724:2x 2x 181

256:2x 2x 2x 2x 2x 2x 2x 2

722:2x 19x 19

642:2x 3x 107

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 2 = 8

Therefore, the value for common factors is 8.

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 = 85911392256/(2x8)

LCM = 85911392256/16

LCM = 5369462016

Thus, we can understand that the LCM of 724,256,722,642 is 5369462016.
