Find LCM of 704,220,511,768 with Prime Factorization
| 2 | 704, 220, 511, 768 |
| 2 | 352, 110, 511, 384 |
| 2 | 176, 55, 511, 192 |
| 2 | 88, 55, 511, 96 |
| 2 | 44, 55, 511, 48 |
| 2 | 22, 55, 511, 24 |
| 11 | 11, 55, 511, 12 |
| 1, 5, 511, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 11 x 1 x 5 x 511 x 12 = 21584640
Therefore, the lowest common multiple of 704,220,511,768 is 21584640.
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.
704 x 220 x 511 x 768 = 60782346240
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.
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
511 : 1, 7, 73, 511
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 704,220,511,768, is 1.
Now, the common factors can be found like this.
704:2x 2x 2x 2x 2x 2x 11
220:2x 2x 5x 11
511:7x 73
768:2x 2x 2x 2x 2x 2x 2x 2x 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 2x 2x 2x 11 = 2816
Therefore, the value for common factors is 2816.
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 = 60782346240/(1x2816)
LCM = 60782346240/2816
LCM = 21584640
Thus, we can understand that the LCM of 704,220,511,768 is 21584640.
