The LCM of 612,979,495,257 is 769905180.
Find LCM of 612,979,495,257 with Prime Factorization
| 3 | 612, 979, 495, 257 |
| 3 | 204, 979, 165, 257 |
| 11 | 68, 979, 55, 257 |
| 68, 89, 5, 257 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 68 x 89 x 5 x 257 = 769905180
Therefore, the lowest common multiple of 612,979,495,257 is 769905180.
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.
612 x 979 x 495 x 257 = 76220612820
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.
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
979 : 1, 11, 89, 979
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,979,495,257, is 1.
Now, the common factors can be found like this.
612:2x 2x 3x 3x 17
979:11x 89
495:3x 3x 5x 11
257:257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11 = 99
Therefore, the value for common factors is 99.
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 = 76220612820/(1x99)
LCM = 76220612820/99
LCM = 769905180
Thus, we can understand that the LCM of 612,979,495,257 is 769905180.
