Calculate the LCM of 615,980,634

Given numbers are 615,980,634

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

The LCM of 615,980,634 is 38211180.

Find LCM of 615,980,634 with Prime Factorization


2 615, 980, 634
5 615, 490, 317
123, 98, 317

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

2 x 5 x 123 x 98 x 317 = 38211180

Therefore, the lowest common multiple of 615,980,634 is 38211180.

LCM Formula to Find Lowest Common Multiple of 615,980,634

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 980 x 634 = 382111800

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

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

634 : 1, 2, 317, 634

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,980,634, is 1.

Now, the common factors can be found like this.

615:3x 5x 41

980:2x 2x 5x 7x 7

634:2x 317

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 382111800/(1x10)

LCM = 382111800/10

LCM = 38211180

Thus, we can understand that the LCM of 615,980,634 is 38211180.
