Given numbers are 630,418,256,277,518

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

The LCM of 630,418,256,277,518 is 172734186240.

Find LCM of 630,418,256,277,518 with Prime Factorization

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

2 x 7 x 45 x 209 x 128 x 277 x 37 = 172734186240

Therefore, the lowest common multiple of 630,418,256,277,518 is 172734186240.

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.

630 x 418 x 256 x 277 x 518 = 9673114429440

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.

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

418 : 1, 2, 11, 19, 22, 38, 209, 418

256 : 1, 2, 4, 8, 16, 32, 64, 128, 256

277 : 1, 277

518 : 1, 2, 7, 14, 37, 74, 259, 518

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,418,256,277,518, is 1.

Now, the common factors can be found like this.

630:2x 3x 3x 5x 7

418:2x 11x 19

256:2x 2x 2x 2x 2x 2x 2x 2

277:277

518:2x 7x 37

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

2x 2x 2x 7 = 56

Therefore, the value for common factors is 56.

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 = 9673114429440/(1x56)

LCM = 9673114429440/56

LCM = 172734186240

Thus, we can understand that the LCM of 630,418,256,277,518 is 172734186240.
