Given numbers are 624,398,502,990

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

The LCM of 624,398,502,990 is 5142749040.

Find LCM of 624,398,502,990 with Prime Factorization

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

2 x 3 x 104 x 199 x 251 x 165 = 5142749040

Therefore, the lowest common multiple of 624,398,502,990 is 5142749040.

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 398 x 502 x 990 = 123425976960

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

398 : 1, 2, 199, 398

502 : 1, 2, 251, 502

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 624,398,502,990, is 2.

Now, the common factors can be found like this.

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

398:2x 199

502:2x 251

990:2x 3x 3x 5x 11

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 = 123425976960/(2x12)

LCM = 123425976960/24

LCM = 5142749040

Thus, we can understand that the LCM of 624,398,502,990 is 5142749040.
