Find LCM of 923,391,703,632,728 with Prime Factorization
| 2 | 923, 391, 703, 632, 728 |
| 2 | 923, 391, 703, 316, 364 |
| 2 | 923, 391, 703, 158, 182 |
| 13 | 923, 391, 703, 79, 91 |
| 71, 391, 703, 79, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 71 x 391 x 703 x 79 x 7 = 1122403214296
Therefore, the lowest common multiple of 923,391,703,632,728 is 1122403214296.
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.
923 x 391 x 703 x 632 x 728 = 116729934286784
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.
923 : 1, 13, 71, 923
391 : 1, 17, 23, 391
703 : 1, 19, 37, 703
632 : 1, 2, 4, 8, 79, 158, 316, 632
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,391,703,632,728, is 1.
Now, the common factors can be found like this.
923:13x 71
391:17x 23
703:19x 37
632:2x 2x 2x 79
728:2x 2x 2x 7x 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 13 = 104
Therefore, the value for common factors is 104.
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 = 116729934286784/(1x104)
LCM = 116729934286784/104
LCM = 1122403214296
Thus, we can understand that the LCM of 923,391,703,632,728 is 1122403214296.
