Find LCM of 704,440,306,561 with Prime Factorization
| 2 | 704, 440, 306, 561 |
| 2 | 352, 220, 153, 561 |
| 2 | 176, 110, 153, 561 |
| 3 | 88, 55, 153, 561 |
| 11 | 88, 55, 51, 187 |
| 17 | 8, 5, 51, 17 |
| 8, 5, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 17 x 8 x 5 x 3 x 1 = 538560
Therefore, the lowest common multiple of 704,440,306,561 is 538560.
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 440 x 306 x 561 = 53175260160
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
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 704,440,306,561, is 1.
Now, the common factors can be found like this.
704:2x 2x 2x 2x 2x 2x 11
440:2x 2x 2x 5x 11
306:2x 3x 3x 17
561:3x 11x 17
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 3x 11x 11x 17 = 98736
Therefore, the value for common factors is 98736.
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 = 53175260160/(1x98736)
LCM = 53175260160/98736
LCM = 538560
Thus, we can understand that the LCM of 704,440,306,561 is 538560.
