The LCM of 389,468,806,747 is 468419796.

Find LCM of 389,468,806,747 with Prime Factorization


2 389, 468, 806, 747
3 389, 234, 403, 747
3 389, 78, 403, 249
13 389, 26, 403, 83
389, 2, 31, 83

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

2 x 3 x 3 x 13 x 389 x 2 x 31 x 83 = 468419796

Therefore, the lowest common multiple of 389,468,806,747 is 468419796.

LCM Formula to Find Lowest Common Multiple of 389,468,806,747

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 468 x 806 x 747 = 109610232264

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

468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468

806 : 1, 2, 13, 26, 31, 62, 403, 806

747 : 1, 3, 9, 83, 249, 747

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 389,468,806,747, is 1.

Now, the common factors can be found like this.

389:389

468:2x 2x 3x 3x 13

806:2x 13x 31

747:3x 3x 83

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

2x 3x 3x 13 = 234

Therefore, the value for common factors is 234.

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 = 109610232264/(1x234)

LCM = 109610232264/234

LCM = 468419796

Thus, we can understand that the LCM of 389,468,806,747 is 468419796.
