Given numbers are 631,393,421,717

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

The LCM of 631,393,421,717 is 24951801477.

Find LCM of 631,393,421,717 with Prime Factorization

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

3 x 631 x 131 x 421 x 239 = 24951801477

Therefore, the lowest common multiple of 631,393,421,717 is 24951801477.

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.

631 x 393 x 421 x 717 = 74855404431

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.

631 : 1, 631

393 : 1, 3, 131, 393

421 : 1, 421

717 : 1, 3, 239, 717

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,393,421,717, is 1.

Now, the common factors can be found like this.

631:631

393:3x 131

421:421

717:3x 239

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3 = 3

Therefore, the value for common factors is 3.

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 = 74855404431/(1x3)

LCM = 74855404431/3

LCM = 24951801477

Thus, we can understand that the LCM of 631,393,421,717 is 24951801477.
