Given numbers are 669,676,328,220

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

The LCM of 669,676,328,220 is 2039620440.

Find LCM of 669,676,328,220 with Prime Factorization

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

2 x 2 x 669 x 169 x 82 x 55 = 2039620440

Therefore, the lowest common multiple of 669,676,328,220 is 2039620440.

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.

669 x 676 x 328 x 220 = 32633927040

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.

669 : 1, 3, 223, 669

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

328 : 1, 2, 4, 8, 41, 82, 164, 328

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,676,328,220, is 1.

Now, the common factors can be found like this.

669:3x 223

676:2x 2x 13x 13

328:2x 2x 2x 41

220:2x 2x 5x 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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 32633927040/(1x16)

LCM = 32633927040/16

LCM = 2039620440

Thus, we can understand that the LCM of 669,676,328,220 is 2039620440.
