Find LCM of 256,495,985,616,817 with Prime Factorization
| 2 | 256, 495, 985, 616, 817 |
| 2 | 128, 495, 985, 308, 817 |
| 2 | 64, 495, 985, 154, 817 |
| 5 | 32, 495, 985, 77, 817 |
| 11 | 32, 99, 197, 77, 817 |
| 32, 9, 197, 7, 817 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 11 x 32 x 9 x 197 x 7 x 817 = 142768200960
Therefore, the lowest common multiple of 256,495,985,616,817 is 142768200960.
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.
256 x 495 x 985 x 616 x 817 = 62818008422400
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.
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
985 : 1, 5, 197, 985
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,495,985,616,817, is 1.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
495:3x 3x 5x 11
985:5x 197
616:2x 2x 2x 7x 11
817:19x 43
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 2x 5x 11 = 440
Therefore, the value for common factors is 440.
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 = 62818008422400/(1x440)
LCM = 62818008422400/440
LCM = 142768200960
Thus, we can understand that the LCM of 256,495,985,616,817 is 142768200960.
