Calculate the LCM of 615,385,226,558

Given numbers are 615,385,226,558

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

The LCM of 615,385,226,558 is 995307390.

Find LCM of 615,385,226,558 with Prime Factorization


2 615, 385, 226, 558
3 615, 385, 113, 279
5 205, 385, 113, 93
41, 77, 113, 93

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

2 x 3 x 5 x 41 x 77 x 113 x 93 = 995307390

Therefore, the lowest common multiple of 615,385,226,558 is 995307390.

LCM Formula to Find Lowest Common Multiple of 615,385,226,558

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.

615 x 385 x 226 x 558 = 29859221700

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.

615 : 1, 3, 5, 15, 41, 123, 205, 615

385 : 1, 5, 7, 11, 35, 55, 77, 385

226 : 1, 2, 113, 226

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,385,226,558, is 1.

Now, the common factors can be found like this.

615:3x 5x 41

385:5x 7x 11

226:2x 113

558:2x 3x 3x 31

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

2x 3x 5 = 30

Therefore, the value for common factors is 30.

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 = 29859221700/(1x30)

LCM = 29859221700/30

LCM = 995307390

Thus, we can understand that the LCM of 615,385,226,558 is 995307390.
