Find LCM of 169,816,638,858,538 with Prime Factorization
| 2 | 169, 816, 638, 858, 538 |
| 3 | 169, 408, 319, 429, 269 |
| 11 | 169, 136, 319, 143, 269 |
| 13 | 169, 136, 29, 13, 269 |
| 1, 136, 29, 13, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 1 x 136 x 29 x 13 x 269 = 11833680144
Therefore, the lowest common multiple of 169,816,638,858,538 is 11833680144.
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.
169 x 816 x 638 x 858 x 538 = 40613190254208
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.
169 : 1, 13, 169
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
638 : 1, 2, 11, 22, 29, 58, 319, 638
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
538 : 1, 2, 269, 538
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,816,638,858,538, is 1.
Now, the common factors can be found like this.
169:13x 13
816:2x 2x 2x 2x 3x 17
638:2x 11x 29
858:2x 3x 11x 13
538:2x 269
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 = 40613190254208/(1x3432)
LCM = 40613190254208/3432
LCM = 11833680144
Thus, we can understand that the LCM of 169,816,638,858,538 is 11833680144.
