Find LCM of 791,704,288,923 with Prime Factorization
| 2 | 791, 704, 288, 923 |
| 2 | 791, 352, 144, 923 |
| 2 | 791, 176, 72, 923 |
| 2 | 791, 88, 36, 923 |
| 2 | 791, 44, 18, 923 |
| 791, 22, 9, 923 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 791 x 22 x 9 x 923 = 4625869248
Therefore, the lowest common multiple of 791,704,288,923 is 4625869248.
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 704 x 288 x 923 = 148027815936
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
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,704,288,923, is 1.
Now, the common factors can be found like this.
791:7x 113
704:2x 2x 2x 2x 2x 2x 11
288:2x 2x 2x 2x 2x 3x 3
923:13x 71
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 2 = 32
Therefore, the value for common factors is 32.
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 = 148027815936/(1x32)
LCM = 148027815936/32
LCM = 4625869248
Thus, we can understand that the LCM of 791,704,288,923 is 4625869248.
