Given numbers are 9945,8517
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 9945,8517 is 1660815.
Find LCM of 9945,8517 with Prime Factorization
| 3 | 9945, 8517 |
| 17 | 3315, 2839 |
| 195, 167 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 195 x 167 = 1660815
Therefore, the lowest common multiple of 9945,8517 is 1660815.
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.
9945 x 8517 = 84701565
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.
9945 : 1, 3, 5, 9, 13, 15, 17, 39, 45, 51, 65, 85, 117, 153, 195, 221, 255, 585, 663, 765, 1105, 1989, 3315, 9945
8517 : 1, 3, 17, 51, 167, 501, 2839, 8517
51 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 9945,8517, is 51.
Now, the common factors can be found like this.
9945:3x 3x 5x 13x 17
8517:3x 17x 167
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
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 = 84701565/(51x1)
LCM = 84701565/51
LCM = 1660815
Thus, we can understand that the LCM of 9945,8517 is 1660815.
