Given numbers are 418,647,718,198

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

The LCM of 418,647,718,198 is 873811026.

Find LCM of 418,647,718,198 with Prime Factorization

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

2 x 11 x 19 x 647 x 359 x 9 = 873811026

Therefore, the lowest common multiple of 418,647,718,198 is 873811026.

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 647 x 718 x 198 = 38447685144

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

647 : 1, 647

718 : 1, 2, 359, 718

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,647,718,198, is 1.

Now, the common factors can be found like this.

418:2x 11x 19

647:647

718:2x 359

198:2x 3x 3x 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 11 = 44

Therefore, the value for common factors is 44.

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 = 38447685144/(1x44)

LCM = 38447685144/44

LCM = 873811026

Thus, we can understand that the LCM of 418,647,718,198 is 873811026.
