Given numbers are 638,849,302,703,720

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

The LCM of 638,849,302,703,720 is 6899885554320.

Find LCM of 638,849,302,703,720 with Prime Factorization

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

2 x 3 x 319 x 283 x 151 x 703 x 120 = 6899885554320

Therefore, the lowest common multiple of 638,849,302,703,720 is 6899885554320.

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.

638 x 849 x 302 x 703 x 720 = 82798626651840

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.

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

849 : 1, 3, 283, 849

302 : 1, 2, 151, 302

703 : 1, 19, 37, 703

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,849,302,703,720, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

849:3x 283

302:2x 151

703:19x 37

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

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 3 = 12

Therefore, the value for common factors is 12.

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 = 82798626651840/(1x12)

LCM = 82798626651840/12

LCM = 6899885554320

Thus, we can understand that the LCM of 638,849,302,703,720 is 6899885554320.
