Given numbers are 720,648,660,447,637

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

The LCM of 720,648,660,447,637 is 6765398640.

Find LCM of 720,648,660,447,637 with Prime Factorization

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

2 x 2 x 2 x 3 x 3 x 5 x 2 x 9 x 11 x 149 x 637 = 6765398640

Therefore, the lowest common multiple of 720,648,660,447,637 is 6765398640.

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.

720 x 648 x 660 x 447 x 637 = 87679566374400

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.

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

447 : 1, 3, 149, 447

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,648,660,447,637, is 1.

Now, the common factors can be found like this.

720:2x 2x 2x 2x 3x 3x 5

648:2x 2x 2x 3x 3x 3x 3

660:2x 2x 3x 5x 11

447:3x 149

637:7x 7x 13

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 2x 2x 3x 3x 3x 3x 5 = 12960

Therefore, the value for common factors is 12960.

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 = 87679566374400/(1x12960)

LCM = 87679566374400/12960

LCM = 6765398640

Thus, we can understand that the LCM of 720,648,660,447,637 is 6765398640.
