Find LCM of 494,921,611,615,920 with Prime Factorization
| 2 | 494, 921, 611, 615, 920 |
| 3 | 247, 921, 611, 615, 460 |
| 5 | 247, 307, 611, 205, 460 |
| 13 | 247, 307, 611, 41, 92 |
| 19, 307, 47, 41, 92 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 19 x 307 x 47 x 41 x 92 = 403298053080
Therefore, the lowest common multiple of 494,921,611,615,920 is 403298053080.
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.
494 x 921 x 611 x 615 x 920 = 157286240701200
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.
494 : 1, 2, 13, 19, 26, 38, 247, 494
921 : 1, 3, 307, 921
611 : 1, 13, 47, 611
615 : 1, 3, 5, 15, 41, 123, 205, 615
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 494,921,611,615,920, is 1.
Now, the common factors can be found like this.
494:2x 13x 19
921:3x 307
611:13x 47
615:3x 5x 41
920:2x 2x 2x 5x 23
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 5x 13 = 390
Therefore, the value for common factors is 390.
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 = 157286240701200/(1x390)
LCM = 157286240701200/390
LCM = 403298053080
Thus, we can understand that the LCM of 494,921,611,615,920 is 403298053080.
