Calculate the LCM of 389,428,631,631,783

Given numbers are 389,428,631,631,783

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

The LCM of 389,428,631,631,783 is 82259201916.

Find LCM of 389,428,631,631,783 with Prime Factorization


631 389, 428, 631, 631, 783
389, 428, 1, 1, 783

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

631 x 389 x 428 x 1 x 1 x 783 = 82259201916

Therefore, the lowest common multiple of 389,428,631,631,783 is 82259201916.

LCM Formula to Find Lowest Common Multiple of 389,428,631,631,783

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.

389 x 428 x 631 x 631 x 783 = 51905556408996

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.

389 : 1, 389

428 : 1, 2, 4, 107, 214, 428

631 : 1, 631

631 : 1, 631

783 : 1, 3, 9, 27, 29, 87, 261, 783

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,428,631,631,783, is 1.

Now, the common factors can be found like this.

389:389

428:2x 2x 107

631:631

631:631

783:3x 3x 3x 29

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 = 51905556408996/(1x631)

LCM = 51905556408996/631

LCM = 82259201916

Thus, we can understand that the LCM of 389,428,631,631,783 is 82259201916.
