Given numbers are 393,398,193,808

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

The LCM of 393,398,193,808 is 12195912408.

Find LCM of 393,398,193,808 with Prime Factorization

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

2 x 393 x 199 x 193 x 404 = 12195912408

Therefore, the lowest common multiple of 393,398,193,808 is 12195912408.

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 398 x 193 x 808 = 24391824816

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

398 : 1, 2, 199, 398

193 : 1, 193

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 393,398,193,808, is 1.

Now, the common factors can be found like this.

393:3x 131

398:2x 199

193:193

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 24391824816/(1x2)

LCM = 24391824816/2

LCM = 12195912408

Thus, we can understand that the LCM of 393,398,193,808 is 12195912408.
