Given numbers are 611,630,687,912

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

The LCM of 611,630,687,912 is 13398643440.

Find LCM of 611,630,687,912 with Prime Factorization

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

2 x 3 x 611 x 105 x 229 x 152 = 13398643440

Therefore, the lowest common multiple of 611,630,687,912 is 13398643440.

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.

611 x 630 x 687 x 912 = 241175581920

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.

611 : 1, 13, 47, 611

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

687 : 1, 3, 229, 687

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 611,630,687,912, is 1.

Now, the common factors can be found like this.

611:13x 47

630:2x 3x 3x 5x 7

687:3x 229

912:2x 2x 2x 2x 3x 19

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 3 = 18

Therefore, the value for common factors is 18.

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 = 241175581920/(1x18)

LCM = 241175581920/18

LCM = 13398643440

Thus, we can understand that the LCM of 611,630,687,912 is 13398643440.
