Find LCM of 791,288,767,624 with Prime Factorization
| 2 | 791, 288, 767, 624 |
| 2 | 791, 144, 767, 312 |
| 2 | 791, 72, 767, 156 |
| 2 | 791, 36, 767, 78 |
| 3 | 791, 18, 767, 39 |
| 13 | 791, 6, 767, 13 |
| 791, 6, 59, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 13 x 791 x 6 x 59 x 1 = 174728736
Therefore, the lowest common multiple of 791,288,767,624 is 174728736.
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 288 x 767 x 624 = 109030731264
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
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
767 : 1, 13, 59, 767
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,288,767,624, is 1.
Now, the common factors can be found like this.
791:7x 113
288:2x 2x 2x 2x 2x 3x 3
767:13x 59
624:2x 2x 2x 2x 3x 13
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 13 = 624
Therefore, the value for common factors is 624.
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 = 109030731264/(1x624)
LCM = 109030731264/624
LCM = 174728736
Thus, we can understand that the LCM of 791,288,767,624 is 174728736.
