Given numbers are 393,909,679,808

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

The LCM of 393,909,679,808 is 646837128.

Find LCM of 393,909,679,808 with Prime Factorization

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

3 x 101 x 131 x 3 x 679 x 8 = 646837128

Therefore, the lowest common multiple of 393,909,679,808 is 646837128.

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 909 x 679 x 808 = 195991649784

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

909 : 1, 3, 9, 101, 303, 909

679 : 1, 7, 97, 679

808 : 1, 2, 4, 8, 101, 202, 404, 808

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 393,909,679,808, is 1.

Now, the common factors can be found like this.

393:3x 131

909:3x 3x 101

679:7x 97

808:2x 2x 2x 101

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

3x 101 = 303

Therefore, the value for common factors is 303.

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 = 195991649784/(1x303)

LCM = 195991649784/303

LCM = 646837128

Thus, we can understand that the LCM of 393,909,679,808 is 646837128.
