Find LCM of 169,198,648,418 with Prime Factorization
| 2 | 169, 198, 648, 418 |
| 3 | 169, 99, 324, 209 |
| 3 | 169, 33, 108, 209 |
| 11 | 169, 11, 36, 209 |
| 169, 1, 36, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 169 x 1 x 36 x 19 = 22888008
Therefore, the lowest common multiple of 169,198,648,418 is 22888008.
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 198 x 648 x 418 = 9063651168
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
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,198,648,418, is 1.
Now, the common factors can be found like this.
169:13x 13
198:2x 3x 3x 11
648:2x 2x 2x 3x 3x 3x 3
418:2x 11x 19
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 3x 11 = 396
Therefore, the value for common factors is 396.
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 = 9063651168/(1x396)
LCM = 9063651168/396
LCM = 22888008
Thus, we can understand that the LCM of 169,198,648,418 is 22888008.
