Find LCM of 729,993,460,243,764 with Prime Factorization
| 2 | 729, 993, 460, 243, 764 |
| 2 | 729, 993, 230, 243, 382 |
| 3 | 729, 993, 115, 243, 191 |
| 3 | 81, 331, 115, 243, 191 |
| 3 | 27, 331, 115, 81, 191 |
| 3 | 9, 331, 115, 27, 191 |
| 3 | 3, 331, 115, 9, 191 |
| 1, 331, 115, 3, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 3 x 3 x 1 x 331 x 115 x 3 x 191 = 21200530140
Therefore, the lowest common multiple of 729,993,460,243,764 is 21200530140.
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 993 x 460 x 243 x 764 = 61820745888240
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
993 : 1, 3, 331, 993
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
243 : 1, 3, 9, 27, 81, 243
764 : 1, 2, 4, 191, 382, 764
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,993,460,243,764, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
993:3x 331
460:2x 2x 5x 23
243:3x 3x 3x 3x 3
764:2x 2x 191
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 3x 3x 3 = 2916
Therefore, the value for common factors is 2916.
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 = 61820745888240/(1x2916)
LCM = 61820745888240/2916
LCM = 21200530140
Thus, we can understand that the LCM of 729,993,460,243,764 is 21200530140.
