Find LCM of 168,108,429,663,993 with Prime Factorization
| 2 | 168, 108, 429, 663, 993 |
| 2 | 84, 54, 429, 663, 993 |
| 3 | 42, 27, 429, 663, 993 |
| 13 | 14, 9, 143, 221, 331 |
| 14, 9, 11, 17, 331 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 14 x 9 x 11 x 17 x 331 = 1216647432
Therefore, the lowest common multiple of 168,108,429,663,993 is 1216647432.
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.
168 x 108 x 429 x 663 x 993 = 5124518983584
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
429 : 1, 3, 11, 13, 33, 39, 143, 429
663 : 1, 3, 13, 17, 39, 51, 221, 663
993 : 1, 3, 331, 993
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,108,429,663,993, is 3.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
108:2x 2x 3x 3x 3
429:3x 11x 13
663:3x 13x 17
993:3x 331
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 3x 13 = 1404
Therefore, the value for common factors is 1404.
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 = 5124518983584/(3x1404)
LCM = 5124518983584/4212
LCM = 1216647432
Thus, we can understand that the LCM of 168,108,429,663,993 is 1216647432.
