Given numbers are 637,840,187,669

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

The LCM of 637,840,187,669 is 3187624440.

Find LCM of 637,840,187,669 with Prime Factorization

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

3 x 7 x 91 x 40 x 187 x 223 = 3187624440

Therefore, the lowest common multiple of 637,840,187,669 is 3187624440.

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.

637 x 840 x 187 x 669 = 66940113240

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.

637 : 1, 7, 13, 49, 91, 637

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

187 : 1, 11, 17, 187

669 : 1, 3, 223, 669

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,840,187,669, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

840:2x 2x 2x 3x 5x 7

187:11x 17

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.

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 66940113240/(1x21)

LCM = 66940113240/21

LCM = 3187624440

Thus, we can understand that the LCM of 637,840,187,669 is 3187624440.
