Calculate the LCM of 631,492,685,648

Given numbers are 631,492,685,648

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

The LCM of 631,492,685,648 is 11483619480.

Find LCM of 631,492,685,648 with Prime Factorization


2 631, 492, 685, 648
2 631, 246, 685, 324
3 631, 123, 685, 162
631, 41, 685, 54

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

2 x 2 x 3 x 631 x 41 x 685 x 54 = 11483619480

Therefore, the lowest common multiple of 631,492,685,648 is 11483619480.

LCM Formula to Find Lowest Common Multiple of 631,492,685,648

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 492 x 685 x 648 = 137803433760

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

492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492

685 : 1, 5, 137, 685

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,492,685,648, is 1.

Now, the common factors can be found like this.

631:631

492:2x 2x 3x 41

685:5x 137

648:2x 2x 2x 3x 3x 3x 3

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 = 137803433760/(1x12)

LCM = 137803433760/12

LCM = 11483619480

Thus, we can understand that the LCM of 631,492,685,648 is 11483619480.
