Given numbers are 631,631,242,442

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

The LCM of 631,631,242,442 is 33747142.

Find LCM of 631,631,242,442 with Prime Factorization

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

2 x 631 x 1 x 1 x 121 x 221 = 33747142

Therefore, the lowest common multiple of 631,631,242,442 is 33747142.

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 631 x 242 x 442 = 42588893204

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

631 : 1, 631

242 : 1, 2, 11, 22, 121, 242

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,631,242,442, is 1.

Now, the common factors can be found like this.

631:631

631:631

242:2x 11x 11

442:2x 13x 17

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

2x 631 = 1262

Therefore, the value for common factors is 1262.

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 = 42588893204/(1x1262)

LCM = 42588893204/1262

LCM = 33747142

Thus, we can understand that the LCM of 631,631,242,442 is 33747142.
