Find LCM of 792,408,791,780,147 with Prime Factorization
| 2 | 792, 408, 791, 780, 147 |
| 2 | 396, 204, 791, 390, 147 |
| 2 | 198, 102, 791, 195, 147 |
| 3 | 99, 51, 791, 195, 147 |
| 7 | 33, 17, 791, 65, 49 |
| 33, 17, 113, 65, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 33 x 17 x 113 x 65 x 7 = 4845760920
Therefore, the lowest common multiple of 792,408,791,780,147 is 4845760920.
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.
792 x 408 x 791 x 780 x 147 = 29307162044160
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.
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
791 : 1, 7, 113, 791
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
147 : 1, 3, 7, 21, 49, 147
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 792,408,791,780,147, is 1.
Now, the common factors can be found like this.
792:2x 2x 2x 3x 3x 11
408:2x 2x 2x 3x 17
791:7x 113
780:2x 2x 3x 5x 13
147:3x 7x 7
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 3x 3x 7 = 6048
Therefore, the value for common factors is 6048.
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 = 29307162044160/(1x6048)
LCM = 29307162044160/6048
LCM = 4845760920
Thus, we can understand that the LCM of 792,408,791,780,147 is 4845760920.
