Find LCM of 731,208,671,240,442 with Prime Factorization
| 2 | 731, 208, 671, 240, 442 |
| 2 | 731, 104, 671, 120, 221 |
| 2 | 731, 52, 671, 60, 221 |
| 2 | 731, 26, 671, 30, 221 |
| 13 | 731, 13, 671, 15, 221 |
| 17 | 731, 1, 671, 15, 17 |
| 43, 1, 671, 15, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 13 x 17 x 43 x 1 x 671 x 15 x 1 = 1530363120
Therefore, the lowest common multiple of 731,208,671,240,442 is 1530363120.
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.
731 x 208 x 671 x 240 x 442 = 10822727984640
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.
731 : 1, 17, 43, 731
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
671 : 1, 11, 61, 671
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,208,671,240,442, is 1.
Now, the common factors can be found like this.
731:17x 43
208:2x 2x 2x 2x 13
671:11x 61
240:2x 2x 2x 2x 3x 5
442:2x 13x 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 2x 13x 17 = 7072
Therefore, the value for common factors is 7072.
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 = 10822727984640/(1x7072)
LCM = 10822727984640/7072
LCM = 1530363120
Thus, we can understand that the LCM of 731,208,671,240,442 is 1530363120.
