Given numbers are 624,655,247,637

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

The LCM of 624,655,247,637 is 380518320.

Find LCM of 624,655,247,637 with Prime Factorization

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

13 x 48 x 655 x 19 x 49 = 380518320

Therefore, the lowest common multiple of 624,655,247,637 is 380518320.

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.

624 x 655 x 247 x 637 = 64307596080

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.

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

655 : 1, 5, 131, 655

247 : 1, 13, 19, 247

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 624,655,247,637, is 1.

Now, the common factors can be found like this.

624:2x 2x 2x 2x 3x 13

655:5x 131

247:13x 19

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.

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 64307596080/(1x169)

LCM = 64307596080/169

LCM = 380518320

Thus, we can understand that the LCM of 624,655,247,637 is 380518320.
