The LCM of 209,858,418,906 is 2461602.
Find LCM of 209,858,418,906 with Prime Factorization
| 2 | 209, 858, 418, 906 |
| 3 | 209, 429, 209, 453 |
| 11 | 209, 143, 209, 151 |
| 19 | 19, 13, 19, 151 |
| 1, 13, 1, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 19 x 1 x 13 x 1 x 151 = 2461602
Therefore, the lowest common multiple of 209,858,418,906 is 2461602.
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 858 x 418 x 906 = 67910675976
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
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
418 : 1, 2, 11, 19, 22, 38, 209, 418
906 : 1, 2, 3, 6, 151, 302, 453, 906
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,858,418,906, is 1.
Now, the common factors can be found like this.
209:11x 19
858:2x 3x 11x 13
418:2x 11x 19
906:2x 3x 151
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 3x 11x 11x 19 = 27588
Therefore, the value for common factors is 27588.
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 = 67910675976/(1x27588)
LCM = 67910675976/27588
LCM = 2461602
Thus, we can understand that the LCM of 209,858,418,906 is 2461602.
