Given numbers are 912,551,143,990

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

The LCM of 912,551,143,990 is 56730960.

Find LCM of 912,551,143,990 with Prime Factorization

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

2 x 3 x 11 x 19 x 8 x 29 x 13 x 15 = 56730960

Therefore, the lowest common multiple of 912,551,143,990 is 56730960.

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.

912 x 551 x 143 x 990 = 71140623840

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.

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

551 : 1, 19, 29, 551

143 : 1, 11, 13, 143

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,551,143,990, is 1.

Now, the common factors can be found like this.

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

551:19x 29

143:11x 13

990:2x 3x 3x 5x 11

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 11x 19 = 1254

Therefore, the value for common factors is 1254.

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 = 71140623840/(1x1254)

LCM = 71140623840/1254

LCM = 56730960

Thus, we can understand that the LCM of 912,551,143,990 is 56730960.
