Find LCM of 725,309,399,841,285 with Prime Factorization
| 3 | 725, 309, 399, 841, 285 |
| 5 | 725, 103, 133, 841, 95 |
| 19 | 145, 103, 133, 841, 19 |
| 29 | 145, 103, 7, 841, 1 |
| 5, 103, 7, 29, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 19 x 29 x 5 x 103 x 7 x 29 x 1 = 864064425
Therefore, the lowest common multiple of 725,309,399,841,285 is 864064425.
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 309 x 399 x 841 x 285 = 21424477417875
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
309 : 1, 3, 103, 309
399 : 1, 3, 7, 19, 21, 57, 133, 399
841 : 1, 29, 841
285 : 1, 3, 5, 15, 19, 57, 95, 285
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 725,309,399,841,285, is 1.
Now, the common factors can be found like this.
725:5x 5x 29
309:3x 103
399:3x 7x 19
841:29x 29
285:3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 19x 29 = 24795
Therefore, the value for common factors is 24795.
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 = 21424477417875/(1x24795)
LCM = 21424477417875/24795
LCM = 864064425
Thus, we can understand that the LCM of 725,309,399,841,285 is 864064425.
