Given numbers are 729,432,393,460
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 729,432,393,460 is 175718160.
Find LCM of 729,432,393,460 with Prime Factorization
| 2 | 729, 432, 393, 460 |
| 2 | 729, 216, 393, 230 |
| 3 | 729, 108, 393, 115 |
| 3 | 243, 36, 131, 115 |
| 3 | 81, 12, 131, 115 |
| 27, 4, 131, 115 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 27 x 4 x 131 x 115 = 175718160
Therefore, the lowest common multiple of 729,432,393,460 is 175718160.
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 432 x 393 x 460 = 56932683840
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
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
393 : 1, 3, 131, 393
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,432,393,460, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
432:2x 2x 2x 2x 3x 3x 3
393:3x 131
460:2x 2x 5x 23
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 3 = 324
Therefore, the value for common factors is 324.
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 = 56932683840/(1x324)
LCM = 56932683840/324
LCM = 175718160
Thus, we can understand that the LCM of 729,432,393,460 is 175718160.
