The LCM of 209,836,748,129 is 1833348.
Find LCM of 209,836,748,129 with Prime Factorization
| 2 | 209, 836, 748, 129 |
| 2 | 209, 418, 374, 129 |
| 11 | 209, 209, 187, 129 |
| 19 | 19, 19, 17, 129 |
| 1, 1, 17, 129 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 19 x 1 x 1 x 17 x 129 = 1833348
Therefore, the lowest common multiple of 209,836,748,129 is 1833348.
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.
209 x 836 x 748 x 129 = 16859468208
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.
209 : 1, 11, 19, 209
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,836,748,129, is 1.
Now, the common factors can be found like this.
209:11x 19
836:2x 2x 11x 19
748:2x 2x 11x 17
129:3x 43
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 11x 11x 19 = 9196
Therefore, the value for common factors is 9196.
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 = 16859468208/(1x9196)
LCM = 16859468208/9196
LCM = 1833348
Thus, we can understand that the LCM of 209,836,748,129 is 1833348.
