Find LCM of 117,988,209,772,198 with Prime Factorization
| 2 | 117, 988, 209, 772, 198 |
| 2 | 117, 494, 209, 386, 99 |
| 3 | 117, 247, 209, 193, 99 |
| 3 | 39, 247, 209, 193, 33 |
| 11 | 13, 247, 209, 193, 11 |
| 13 | 13, 247, 19, 193, 1 |
| 19 | 1, 19, 19, 193, 1 |
| 1, 1, 1, 193, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 13 x 19 x 1 x 1 x 1 x 193 x 1 = 18877716
Therefore, the lowest common multiple of 117,988,209,772,198 is 18877716.
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.
117 x 988 x 209 x 772 x 198 = 3692934314784
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.
117 : 1, 3, 9, 13, 39, 117
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
209 : 1, 11, 19, 209
772 : 1, 2, 4, 193, 386, 772
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,988,209,772,198, is 1.
Now, the common factors can be found like this.
117:3x 3x 13
988:2x 2x 13x 19
209:11x 19
772:2x 2x 193
198:2x 3x 3x 11
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 3x 11x 13x 19 = 195624
Therefore, the value for common factors is 195624.
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 = 3692934314784/(1x195624)
LCM = 3692934314784/195624
LCM = 18877716
Thus, we can understand that the LCM of 117,988,209,772,198 is 18877716.
