Calculate the LCM of 615,795,746,520

Given numbers are 615,795,746,520

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

The LCM of 615,795,746,520 is 1264425240.

Find LCM of 615,795,746,520 with Prime Factorization


2 615, 795, 746, 520
3 615, 795, 373, 260
5 205, 265, 373, 260
41, 53, 373, 52

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

2 x 3 x 5 x 41 x 53 x 373 x 52 = 1264425240

Therefore, the lowest common multiple of 615,795,746,520 is 1264425240.

LCM Formula to Find Lowest Common Multiple of 615,795,746,520

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 795 x 746 x 520 = 189663786000

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

795 : 1, 3, 5, 15, 53, 159, 265, 795

746 : 1, 2, 373, 746

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,795,746,520, is 1.

Now, the common factors can be found like this.

615:3x 5x 41

795:3x 5x 53

746:2x 373

520:2x 2x 2x 5x 13

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 5x 5 = 150

Therefore, the value for common factors is 150.

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 = 189663786000/(1x150)

LCM = 189663786000/150

LCM = 1264425240

Thus, we can understand that the LCM of 615,795,746,520 is 1264425240.
