Calculate the LCM of 615,686,915,113

Given numbers are 615,686,915,113

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

The LCM of 615,686,915,113 is 2908087770.

Find LCM of 615,686,915,113 with Prime Factorization


3 615, 686, 915, 113
5 205, 686, 305, 113
41, 686, 61, 113

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

3 x 5 x 41 x 686 x 61 x 113 = 2908087770

Therefore, the lowest common multiple of 615,686,915,113 is 2908087770.

LCM Formula to Find Lowest Common Multiple of 615,686,915,113

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 686 x 915 x 113 = 43621316550

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

686 : 1, 2, 7, 14, 49, 98, 343, 686

915 : 1, 3, 5, 15, 61, 183, 305, 915

113 : 1, 113

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,686,915,113, is 1.

Now, the common factors can be found like this.

615:3x 5x 41

686:2x 7x 7x 7

915:3x 5x 61

113:113

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 43621316550/(1x15)

LCM = 43621316550/15

LCM = 2908087770

Thus, we can understand that the LCM of 615,686,915,113 is 2908087770.
