Find LCM of 791,124,816,288 with Prime Factorization
| 2 | 791, 124, 816, 288 |
| 2 | 791, 62, 408, 144 |
| 2 | 791, 31, 204, 72 |
| 2 | 791, 31, 102, 36 |
| 3 | 791, 31, 51, 18 |
| 791, 31, 17, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 791 x 31 x 17 x 6 = 120054816
Therefore, the lowest common multiple of 791,124,816,288 is 120054816.
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.
791 x 124 x 816 x 288 = 23050524672
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.
791 : 1, 7, 113, 791
124 : 1, 2, 4, 31, 62, 124
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,124,816,288, is 1.
Now, the common factors can be found like this.
791:7x 113
124:2x 2x 31
816:2x 2x 2x 2x 3x 17
288:2x 2x 2x 2x 2x 3x 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 3 = 192
Therefore, the value for common factors is 192.
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 = 23050524672/(1x192)
LCM = 23050524672/192
LCM = 120054816
Thus, we can understand that the LCM of 791,124,816,288 is 120054816.
