Find LCM of 256,747,861,352 with Prime Factorization
| 2 | 256, 747, 861, 352 |
| 2 | 128, 747, 861, 176 |
| 2 | 64, 747, 861, 88 |
| 2 | 32, 747, 861, 44 |
| 2 | 16, 747, 861, 22 |
| 3 | 8, 747, 861, 11 |
| 8, 249, 287, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 8 x 249 x 287 x 11 = 603719424
Therefore, the lowest common multiple of 256,747,861,352 is 603719424.
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 747 x 861 x 352 = 57957064704
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
747 : 1, 3, 9, 83, 249, 747
861 : 1, 3, 7, 21, 41, 123, 287, 861
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,747,861,352, is 1.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
747:3x 3x 83
861:3x 7x 41
352:2x 2x 2x 2x 2x 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 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 = 57957064704/(1x96)
LCM = 57957064704/96
LCM = 603719424
Thus, we can understand that the LCM of 256,747,861,352 is 603719424.
