Find LCM of 725,406,315,558 with Prime Factorization
| 2 | 725, 406, 315, 558 |
| 3 | 725, 203, 315, 279 |
| 3 | 725, 203, 105, 93 |
| 5 | 725, 203, 35, 31 |
| 7 | 145, 203, 7, 31 |
| 29 | 145, 29, 1, 31 |
| 5, 1, 1, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 29 x 5 x 1 x 1 x 31 = 2831850
Therefore, the lowest common multiple of 725,406,315,558 is 2831850.
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.
725 x 406 x 315 x 558 = 51737899500
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.
725 : 1, 5, 25, 29, 145, 725
406 : 1, 2, 7, 14, 29, 58, 203, 406
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 725,406,315,558, is 1.
Now, the common factors can be found like this.
725:5x 5x 29
406:2x 7x 29
315:3x 3x 5x 7
558:2x 3x 3x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 7x 29 = 18270
Therefore, the value for common factors is 18270.
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 = 51737899500/(1x18270)
LCM = 51737899500/18270
LCM = 2831850
Thus, we can understand that the LCM of 725,406,315,558 is 2831850.
