Given numbers are 393,977,811,655

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

The LCM of 393,977,811,655 is 1556961855.

Find LCM of 393,977,811,655 with Prime Factorization

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

131 x 3 x 977 x 811 x 5 = 1556961855

Therefore, the lowest common multiple of 393,977,811,655 is 1556961855.

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.

393 x 977 x 811 x 655 = 203962003005

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.

393 : 1, 3, 131, 393

977 : 1, 977

811 : 1, 811

655 : 1, 5, 131, 655

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,977,811,655, is 1.

Now, the common factors can be found like this.

393:3x 131

977:977

811:811

655:5x 131

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

131 = 131

Therefore, the value for common factors is 131.

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 = 203962003005/(1x131)

LCM = 203962003005/131

LCM = 1556961855

Thus, we can understand that the LCM of 393,977,811,655 is 1556961855.
