The LCM of 492,768,615,339 is 17790720.
Find LCM of 492,768,615,339 with Prime Factorization
| 2 | 492, 768, 615, 339 |
| 2 | 246, 384, 615, 339 |
| 3 | 123, 192, 615, 339 |
| 41 | 41, 64, 205, 113 |
| 1, 64, 5, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 41 x 1 x 64 x 5 x 113 = 17790720
Therefore, the lowest common multiple of 492,768,615,339 is 17790720.
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.
492 x 768 x 615 x 339 = 78777308160
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.
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
615 : 1, 3, 5, 15, 41, 123, 205, 615
339 : 1, 3, 113, 339
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 492,768,615,339, is 3.
Now, the common factors can be found like this.
492:2x 2x 3x 41
768:2x 2x 2x 2x 2x 2x 2x 2x 3
615:3x 5x 41
339:3x 113
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 3x 3x 41 = 1476
Therefore, the value for common factors is 1476.
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 = 78777308160/(3x1476)
LCM = 78777308160/4428
LCM = 17790720
Thus, we can understand that the LCM of 492,768,615,339 is 17790720.
