Find LCM of 678,693,324,239,405 with Prime Factorization
| 2 | 678, 693, 324, 239, 405 |
| 3 | 339, 693, 162, 239, 405 |
| 3 | 113, 231, 54, 239, 135 |
| 3 | 113, 77, 18, 239, 45 |
| 3 | 113, 77, 6, 239, 15 |
| 113, 77, 2, 239, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 113 x 77 x 2 x 239 x 5 = 3368853180
Therefore, the lowest common multiple of 678,693,324,239,405 is 3368853180.
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.
678 x 693 x 324 x 239 x 405 = 14735363809320
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
324 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 324
239 : 1, 239
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,693,324,239,405, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
693:3x 3x 7x 11
324:2x 2x 3x 3x 3x 3
239:239
405:3x 3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 3x 3x 3 = 4374
Therefore, the value for common factors is 4374.
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 = 14735363809320/(1x4374)
LCM = 14735363809320/4374
LCM = 3368853180
Thus, we can understand that the LCM of 678,693,324,239,405 is 3368853180.
