The LCM of 815,418,791,612 is 82457810820.

Find LCM of 815,418,791,612 with Prime Factorization


2 815, 418, 791, 612
815, 209, 791, 306

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

2 x 815 x 209 x 791 x 306 = 82457810820

Therefore, the lowest common multiple of 815,418,791,612 is 82457810820.

LCM Formula to Find Lowest Common Multiple of 815,418,791,612

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.

815 x 418 x 791 x 612 = 164915621640

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.

815 : 1, 5, 163, 815

418 : 1, 2, 11, 19, 22, 38, 209, 418

791 : 1, 7, 113, 791

612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,418,791,612, is 1.

Now, the common factors can be found like this.

815:5x 163

418:2x 11x 19

791:7x 113

612:2x 2x 3x 3x 17

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

2 = 2

Therefore, the value for common factors is 2.

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 = 164915621640/(1x2)

LCM = 164915621640/2

LCM = 82457810820

Thus, we can understand that the LCM of 815,418,791,612 is 82457810820.
