Find LCM of 256,688,592,389,387 with Prime Factorization
| 2 | 256, 688, 592, 389, 387 |
| 2 | 128, 344, 296, 389, 387 |
| 2 | 64, 172, 148, 389, 387 |
| 2 | 32, 86, 74, 389, 387 |
| 43 | 16, 43, 37, 389, 387 |
| 16, 1, 37, 389, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 43 x 16 x 1 x 37 x 389 x 9 = 1425943296
Therefore, the lowest common multiple of 256,688,592,389,387 is 1425943296.
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 688 x 592 x 389 x 387 = 15696783802368
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
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
592 : 1, 2, 4, 8, 16, 37, 74, 148, 296, 592
389 : 1, 389
387 : 1, 3, 9, 43, 129, 387
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 256,688,592,389,387, is 1.
Now, the common factors can be found like this.
256:2x 2x 2x 2x 2x 2x 2x 2
688:2x 2x 2x 2x 43
592:2x 2x 2x 2x 37
389:389
387:3x 3x 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 2x 2x 2x 2x 2x 43 = 11008
Therefore, the value for common factors is 11008.
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 = 15696783802368/(1x11008)
LCM = 15696783802368/11008
LCM = 1425943296
Thus, we can understand that the LCM of 256,688,592,389,387 is 1425943296.
