Find LCM of 271,728,442,975,455 with Prime Factorization
| 2 | 271, 728, 442, 975, 455 |
| 5 | 271, 364, 221, 975, 455 |
| 7 | 271, 364, 221, 195, 91 |
| 13 | 271, 52, 221, 195, 13 |
| 271, 4, 17, 15, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 13 x 271 x 4 x 17 x 15 x 1 = 251542200
Therefore, the lowest common multiple of 271,728,442,975,455 is 251542200.
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.
271 x 728 x 442 x 975 x 455 = 38684674938000
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.
271 : 1, 271
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
442 : 1, 2, 13, 17, 26, 34, 221, 442
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 271,728,442,975,455, is 1.
Now, the common factors can be found like this.
271:271
728:2x 2x 2x 7x 13
442:2x 13x 17
975:3x 5x 5x 13
455:5x 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 5x 7x 13x 13x 13 = 153790
Therefore, the value for common factors is 153790.
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 = 38684674938000/(1x153790)
LCM = 38684674938000/153790
LCM = 251542200
Thus, we can understand that the LCM of 271,728,442,975,455 is 251542200.
