Find LCM of 874,288,687,656 with Prime Factorization
| 2 | 874, 288, 687, 656 |
| 2 | 437, 144, 687, 328 |
| 2 | 437, 72, 687, 164 |
| 2 | 437, 36, 687, 82 |
| 3 | 437, 18, 687, 41 |
| 437, 6, 229, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 437 x 6 x 229 x 41 = 1181661984
Therefore, the lowest common multiple of 874,288,687,656 is 1181661984.
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.
874 x 288 x 687 x 656 = 113439550464
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
687 : 1, 3, 229, 687
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,288,687,656, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
288:2x 2x 2x 2x 2x 3x 3
687:3x 229
656:2x 2x 2x 2x 41
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 3 = 96
Therefore, the value for common factors is 96.
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 = 113439550464/(1x96)
LCM = 113439550464/96
LCM = 1181661984
Thus, we can understand that the LCM of 874,288,687,656 is 1181661984.
