Calculate the LCM of 631,631,645,439

Given numbers are 631,631,645,439

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

The LCM of 631,631,645,439 is 178670805.

Find LCM of 631,631,645,439 with Prime Factorization


631 631, 631, 645, 439
1, 1, 645, 439

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

631 x 1 x 1 x 645 x 439 = 178670805

Therefore, the lowest common multiple of 631,631,645,439 is 178670805.

LCM Formula to Find Lowest Common Multiple of 631,631,645,439

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 645 x 439 = 112741277955

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

645 : 1, 3, 5, 15, 43, 129, 215, 645

439 : 1, 439

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,631,645,439, is 1.

Now, the common factors can be found like this.

631:631

631:631

645:3x 5x 43

439:439

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

631 = 631

Therefore, the value for common factors is 631.

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 = 112741277955/(1x631)

LCM = 112741277955/631

LCM = 178670805

Thus, we can understand that the LCM of 631,631,645,439 is 178670805.
