Given numbers are 418,173,173,393

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

The LCM of 418,173,173,393 is 28419402.

Find LCM of 418,173,173,393 with Prime Factorization

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

173 x 418 x 1 x 1 x 393 = 28419402

Therefore, the lowest common multiple of 418,173,173,393 is 28419402.

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.

418 x 173 x 173 x 393 = 4916556546

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.

418 : 1, 2, 11, 19, 22, 38, 209, 418

173 : 1, 173

173 : 1, 173

393 : 1, 3, 131, 393

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,173,173,393, is 1.

Now, the common factors can be found like this.

418:2x 11x 19

173:173

173:173

393:3x 131

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

173 = 173

Therefore, the value for common factors is 173.

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 = 4916556546/(1x173)

LCM = 4916556546/173

LCM = 28419402

Thus, we can understand that the LCM of 418,173,173,393 is 28419402.
