Given numbers are 808,646,220,669

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

The LCM of 808,646,220,669 is 9602906280.

Find LCM of 808,646,220,669 with Prime Factorization

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

2 x 2 x 202 x 323 x 55 x 669 = 9602906280

Therefore, the lowest common multiple of 808,646,220,669 is 9602906280.

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.

808 x 646 x 220 x 669 = 76823250240

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.

808 : 1, 2, 4, 8, 101, 202, 404, 808

646 : 1, 2, 17, 19, 34, 38, 323, 646

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

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,646,220,669, is 1.

Now, the common factors can be found like this.

808:2x 2x 2x 101

646:2x 17x 19

220:2x 2x 5x 11

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 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 76823250240/(1x8)

LCM = 76823250240/8

LCM = 9602906280

Thus, we can understand that the LCM of 808,646,220,669 is 9602906280.

Here are some samples of LCM of two or more Numbers calculations.
