Find LCM of 729,422,408,332,640 with Prime Factorization
| 2 | 729, 422, 408, 332, 640 |
| 2 | 729, 211, 204, 166, 320 |
| 2 | 729, 211, 102, 83, 160 |
| 3 | 729, 211, 51, 83, 80 |
| 243, 211, 17, 83, 80 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 243 x 211 x 17 x 83 x 80 = 138904709760
Therefore, the lowest common multiple of 729,422,408,332,640 is 138904709760.
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.
729 x 422 x 408 x 332 x 640 = 26669704273920
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.
729 : 1, 3, 9, 27, 81, 243, 729
422 : 1, 2, 211, 422
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
332 : 1, 2, 4, 83, 166, 332
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,422,408,332,640, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
422:2x 211
408:2x 2x 2x 3x 17
332:2x 2x 83
640:2x 2x 2x 2x 2x 2x 2x 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 2x 2x 2x 2x 2x 3 = 192
Therefore, the value for common factors is 192.
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 = 26669704273920/(1x192)
LCM = 26669704273920/192
LCM = 138904709760
Thus, we can understand that the LCM of 729,422,408,332,640 is 138904709760.
