Calculate the LCM of 481,388,778,756

Given numbers are 481,388,778,756

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

The LCM of 481,388,778,756 is 13721077188.

Find LCM of 481,388,778,756 with Prime Factorization


2 481, 388, 778, 756
2 481, 194, 389, 378
481, 97, 389, 189

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

2 x 2 x 481 x 97 x 389 x 189 = 13721077188

Therefore, the lowest common multiple of 481,388,778,756 is 13721077188.

LCM Formula to Find Lowest Common Multiple of 481,388,778,756

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.

481 x 388 x 778 x 756 = 109768617504

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.

481 : 1, 13, 37, 481

388 : 1, 2, 4, 97, 194, 388

778 : 1, 2, 389, 778

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,388,778,756, is 1.

Now, the common factors can be found like this.

481:13x 37

388:2x 2x 97

778:2x 389

756:2x 2x 3x 3x 3x 7

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 2 = 8

Therefore, the value for common factors is 8.

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 = 109768617504/(1x8)

LCM = 109768617504/8

LCM = 13721077188

Thus, we can understand that the LCM of 481,388,778,756 is 13721077188.
