Given numbers are 615,826,321,345,630

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

The LCM of 615,826,321,345,630 is 3750490170.

Find LCM of 615,826,321,345,630 with Prime Factorization

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

2 x 3 x 5 x 7 x 41 x 59 x 107 x 23 x 3 = 3750490170

Therefore, the lowest common multiple of 615,826,321,345,630 is 3750490170.

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 826 x 321 x 345 x 630 = 35442132106500

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

826 : 1, 2, 7, 14, 59, 118, 413, 826

321 : 1, 3, 107, 321

345 : 1, 3, 5, 15, 23, 69, 115, 345

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,826,321,345,630, is 1.

Now, the common factors can be found like this.

615:3x 5x 41

826:2x 7x 59

321:3x 107

345:3x 5x 23

630:2x 3x 3x 5x 7

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 3x 3x 5x 5x 7 = 9450

Therefore, the value for common factors is 9450.

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 = 35442132106500/(1x9450)

LCM = 35442132106500/9450

LCM = 3750490170

Thus, we can understand that the LCM of 615,826,321,345,630 is 3750490170.
