Find LCM of 145,665,268,816,456 with Prime Factorization
| 2 | 145, 665, 268, 816, 456 |
| 2 | 145, 665, 134, 408, 228 |
| 2 | 145, 665, 67, 204, 114 |
| 3 | 145, 665, 67, 102, 57 |
| 5 | 145, 665, 67, 34, 19 |
| 19 | 29, 133, 67, 34, 19 |
| 29, 7, 67, 34, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 19 x 29 x 7 x 67 x 34 x 1 = 1054349520
Therefore, the lowest common multiple of 145,665,268,816,456 is 1054349520.
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.
145 x 665 x 268 x 816 x 456 = 9615667622400
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.
145 : 1, 5, 29, 145
665 : 1, 5, 7, 19, 35, 95, 133, 665
268 : 1, 2, 4, 67, 134, 268
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 145,665,268,816,456, is 1.
Now, the common factors can be found like this.
145:5x 29
665:5x 7x 19
268:2x 2x 67
816:2x 2x 2x 2x 3x 17
456:2x 2x 2x 3x 19
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 3x 5x 19 = 9120
Therefore, the value for common factors is 9120.
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 = 9615667622400/(1x9120)
LCM = 9615667622400/9120
LCM = 1054349520
Thus, we can understand that the LCM of 145,665,268,816,456 is 1054349520.
