Given numbers are 518,630,312,561

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

The LCM of 518,630,312,561 is 226666440.

Find LCM of 518,630,312,561 with Prime Factorization

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

2 x 3 x 7 x 37 x 15 x 52 x 187 = 226666440

Therefore, the lowest common multiple of 518,630,312,561 is 226666440.

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.

518 x 630 x 312 x 561 = 57119942880

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.

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

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

312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312

561 : 1, 3, 11, 17, 33, 51, 187, 561

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,630,312,561, is 1.

Now, the common factors can be found like this.

518:2x 7x 37

630:2x 3x 3x 5x 7

312:2x 2x 2x 3x 13

561:3x 11x 17

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 3x 3x 7 = 252

Therefore, the value for common factors is 252.

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 = 57119942880/(1x252)

LCM = 57119942880/252

LCM = 226666440

Thus, we can understand that the LCM of 518,630,312,561 is 226666440.
