Given numbers are 990,836,946,804,231

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

The LCM of 990,836,946,804,231 is 758682540.

Find LCM of 990,836,946,804,231 with Prime Factorization

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

2 x 2 x 3 x 11 x 15 x 19 x 43 x 67 x 7 = 758682540

Therefore, the lowest common multiple of 990,836,946,804,231 is 758682540.

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.

990 x 836 x 946 x 804 x 231 = 145412130346560

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.

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

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

946 : 1, 2, 11, 22, 43, 86, 473, 946

804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804

231 : 1, 3, 7, 11, 21, 33, 77, 231

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,836,946,804,231, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

836:2x 2x 11x 19

946:2x 11x 43

804:2x 2x 3x 67

231:3x 7x 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 3x 11x 11x 11 = 191664

Therefore, the value for common factors is 191664.

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 = 145412130346560/(1x191664)

LCM = 145412130346560/191664

LCM = 758682540

Thus, we can understand that the LCM of 990,836,946,804,231 is 758682540.
