Calculate the LCM of 641,830,428,512,722

Given numbers are 641,830,428,512,722

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

The LCM of 641,830,428,512,722 is 5260985039360.

Find LCM of 641,830,428,512,722 with Prime Factorization


2 641, 830, 428, 512, 722
2 641, 415, 214, 256, 361
641, 415, 107, 128, 361

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

2 x 2 x 641 x 415 x 107 x 128 x 361 = 5260985039360

Therefore, the lowest common multiple of 641,830,428,512,722 is 5260985039360.

LCM Formula to Find Lowest Common Multiple of 641,830,428,512,722

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.

641 x 830 x 428 x 512 x 722 = 84175760629760

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.

641 : 1, 641

830 : 1, 2, 5, 10, 83, 166, 415, 830

428 : 1, 2, 4, 107, 214, 428

512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,830,428,512,722, is 1.

Now, the common factors can be found like this.

641:641

830:2x 5x 83

428:2x 2x 107

512:2x 2x 2x 2x 2x 2x 2x 2x 2

722:2x 19x 19

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 2 = 16

Therefore, the value for common factors is 16.

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 = 84175760629760/(1x16)

LCM = 84175760629760/16

LCM = 5260985039360

Thus, we can understand that the LCM of 641,830,428,512,722 is 5260985039360.
