The LCM of 845,331,665,494 is 74398870.

Find LCM of 845,331,665,494 with Prime Factorization


5 845, 331, 665, 494
13 169, 331, 133, 494
19 13, 331, 133, 38
13, 331, 7, 2

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

5 x 13 x 19 x 13 x 331 x 7 x 2 = 74398870

Therefore, the lowest common multiple of 845,331,665,494 is 74398870.

LCM Formula to Find Lowest Common Multiple of 845,331,665,494

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.

845 x 331 x 665 x 494 = 91882604450

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.

845 : 1, 5, 13, 65, 169, 845

331 : 1, 331

665 : 1, 5, 7, 19, 35, 95, 133, 665

494 : 1, 2, 13, 19, 26, 38, 247, 494

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,331,665,494, is 1.

Now, the common factors can be found like this.

845:5x 13x 13

331:331

665:5x 7x 19

494:2x 13x 19

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

5x 13x 19 = 1235

Therefore, the value for common factors is 1235.

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 = 91882604450/(1x1235)

LCM = 91882604450/1235

LCM = 74398870

Thus, we can understand that the LCM of 845,331,665,494 is 74398870.
