The LCM of 495,615,988,990 is 20051460.
Find LCM of 495,615,988,990 with Prime Factorization
| 2 | 495, 615, 988, 990 |
| 3 | 495, 615, 494, 495 |
| 3 | 165, 205, 494, 165 |
| 5 | 55, 205, 494, 55 |
| 11 | 11, 41, 494, 11 |
| 1, 41, 494, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 1 x 41 x 494 x 1 = 20051460
Therefore, the lowest common multiple of 495,615,988,990 is 20051460.
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.
495 x 615 x 988 x 990 = 297764181000
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.
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
615 : 1, 3, 5, 15, 41, 123, 205, 615
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 495,615,988,990, is 1.
Now, the common factors can be found like this.
495:3x 3x 5x 11
615:3x 5x 41
988:2x 2x 13x 19
990:2x 3x 3x 5x 11
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 3x 5x 5x 11 = 14850
Therefore, the value for common factors is 14850.
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 = 297764181000/(1x14850)
LCM = 297764181000/14850
LCM = 20051460
Thus, we can understand that the LCM of 495,615,988,990 is 20051460.
