Given numbers are 812,631,398,528,990

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

The LCM of 812,631,398,528,990 is 201884815440.

Find LCM of 812,631,398,528,990 with Prime Factorization

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

2 x 2 x 3 x 11 x 203 x 631 x 199 x 4 x 15 = 201884815440

Therefore, the lowest common multiple of 812,631,398,528,990 is 201884815440.

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.

812 x 631 x 398 x 528 x 990 = 106595182552320

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.

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

631 : 1, 631

398 : 1, 2, 199, 398

528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528

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 812,631,398,528,990, is 1.

Now, the common factors can be found like this.

812:2x 2x 7x 29

631:631

398:2x 199

528:2x 2x 2x 2x 3x 11

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 2x 2x 2x 3x 11 = 528

Therefore, the value for common factors is 528.

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 = 106595182552320/(1x528)

LCM = 106595182552320/528

LCM = 201884815440

Thus, we can understand that the LCM of 812,631,398,528,990 is 201884815440.
