Find LCM of 789,714,578,637,388 with Prime Factorization
| 2 | 789, 714, 578, 637, 388 |
| 3 | 789, 357, 289, 637, 194 |
| 7 | 263, 119, 289, 637, 194 |
| 17 | 263, 17, 289, 91, 194 |
| 263, 1, 17, 91, 194 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 263 x 1 x 17 x 91 x 194 = 56356758276
Therefore, the lowest common multiple of 789,714,578,637,388 is 56356758276.
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.
789 x 714 x 578 x 637 x 388 = 80477450818128
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.
789 : 1, 3, 263, 789
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
578 : 1, 2, 17, 34, 289, 578
637 : 1, 7, 13, 49, 91, 637
388 : 1, 2, 4, 97, 194, 388
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,714,578,637,388, is 1.
Now, the common factors can be found like this.
789:3x 263
714:2x 3x 7x 17
578:2x 17x 17
637:7x 7x 13
388:2x 2x 97
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 3x 7x 17 = 1428
Therefore, the value for common factors is 1428.
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 = 80477450818128/(1x1428)
LCM = 80477450818128/1428
LCM = 56356758276
Thus, we can understand that the LCM of 789,714,578,637,388 is 56356758276.
