Given numbers are 218,638,718,669

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

The LCM of 218,638,718,669 is 16701971682.

Find LCM of 218,638,718,669 with Prime Factorization

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

2 x 109 x 319 x 359 x 669 = 16701971682

Therefore, the lowest common multiple of 218,638,718,669 is 16701971682.

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.

218 x 638 x 718 x 669 = 66807886728

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.

218 : 1, 2, 109, 218

638 : 1, 2, 11, 22, 29, 58, 319, 638

718 : 1, 2, 359, 718

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,638,718,669, is 1.

Now, the common factors can be found like this.

218:2x 109

638:2x 11x 29

718:2x 359

669:3x 223

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 66807886728/(1x4)

LCM = 66807886728/4

LCM = 16701971682

Thus, we can understand that the LCM of 218,638,718,669 is 16701971682.
