Find LCM of 813,172,572,286,417 with Prime Factorization
| 2 | 813, 172, 572, 286, 417 |
| 2 | 813, 86, 286, 143, 417 |
| 3 | 813, 43, 143, 143, 417 |
| 11 | 271, 43, 143, 143, 139 |
| 13 | 271, 43, 13, 13, 139 |
| 271, 43, 1, 1, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 13 x 271 x 43 x 1 x 1 x 139 = 2779520172
Therefore, the lowest common multiple of 813,172,572,286,417 is 2779520172.
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.
813 x 172 x 572 x 286 x 417 = 9539313230304
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.
813 : 1, 3, 271, 813
172 : 1, 2, 4, 43, 86, 172
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
286 : 1, 2, 11, 13, 22, 26, 143, 286
417 : 1, 3, 139, 417
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,172,572,286,417, is 1.
Now, the common factors can be found like this.
813:3x 271
172:2x 2x 43
572:2x 2x 11x 13
286:2x 11x 13
417:3x 139
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 3x 11x 13 = 3432
Therefore, the value for common factors is 3432.
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 = 9539313230304/(1x3432)
LCM = 9539313230304/3432
LCM = 2779520172
Thus, we can understand that the LCM of 813,172,572,286,417 is 2779520172.
