Find LCM of 771,256,117,288 with Prime Factorization
| 2 | 771, 256, 117, 288 |
| 2 | 771, 128, 117, 144 |
| 2 | 771, 64, 117, 72 |
| 2 | 771, 32, 117, 36 |
| 2 | 771, 16, 117, 18 |
| 3 | 771, 8, 117, 9 |
| 3 | 257, 8, 39, 3 |
| 257, 8, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 3 x 257 x 8 x 13 x 1 = 7697664
Therefore, the lowest common multiple of 771,256,117,288 is 7697664.
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.
771 x 256 x 117 x 288 = 6650781696
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.
771 : 1, 3, 257, 771
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
117 : 1, 3, 9, 13, 39, 117
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,256,117,288, is 1.
Now, the common factors can be found like this.
771:3x 257
256:2x 2x 2x 2x 2x 2x 2x 2
117:3x 3x 13
288:2x 2x 2x 2x 2x 3x 3
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 2x 2x 3x 3x 3 = 864
Therefore, the value for common factors is 864.
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 = 6650781696/(1x864)
LCM = 6650781696/864
LCM = 7697664
Thus, we can understand that the LCM of 771,256,117,288 is 7697664.
