Find LCM of 325,656,558,391,680 with Prime Factorization
| 2 | 325, 656, 558, 391, 680 |
| 2 | 325, 328, 279, 391, 340 |
| 2 | 325, 164, 279, 391, 170 |
| 5 | 325, 82, 279, 391, 85 |
| 17 | 65, 82, 279, 391, 17 |
| 65, 82, 279, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 17 x 65 x 82 x 279 x 23 x 1 = 23257774800
Therefore, the lowest common multiple of 325,656,558,391,680 is 23257774800.
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.
325 x 656 x 558 x 391 x 680 = 31630573728000
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.
325 : 1, 5, 13, 25, 65, 325
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
391 : 1, 17, 23, 391
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 325,656,558,391,680, is 1.
Now, the common factors can be found like this.
325:5x 5x 13
656:2x 2x 2x 2x 41
558:2x 3x 3x 31
391:17x 23
680:2x 2x 2x 5x 17
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 5x 17 = 1360
Therefore, the value for common factors is 1360.
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 = 31630573728000/(1x1360)
LCM = 31630573728000/1360
LCM = 23257774800
Thus, we can understand that the LCM of 325,656,558,391,680 is 23257774800.
