Find LCM of 729,486,618,585,520 with Prime Factorization
| 2 | 729, 486, 618, 585, 520 |
| 3 | 729, 243, 309, 585, 260 |
| 3 | 81, 243, 103, 195, 260 |
| 3 | 27, 81, 103, 65, 260 |
| 3 | 9, 27, 103, 65, 260 |
| 3 | 3, 9, 103, 65, 260 |
| 5 | 1, 3, 103, 65, 260 |
| 13 | 1, 3, 103, 13, 52 |
| 1, 3, 103, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 3 x 5 x 13 x 1 x 3 x 103 x 1 x 4 = 39045240
Therefore, the lowest common multiple of 729,486,618,585,520 is 39045240.
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 486 x 618 x 585 x 520 = 66605713106400
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
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
618 : 1, 2, 3, 6, 103, 206, 309, 618
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,486,618,585,520, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
486:2x 3x 3x 3x 3x 3
618:2x 3x 103
585:3x 3x 5x 13
520:2x 2x 2x 5x 13
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 3x 3x 3x 5x 13 = 1705860
Therefore, the value for common factors is 1705860.
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 = 66605713106400/(1x1705860)
LCM = 66605713106400/1705860
LCM = 39045240
Thus, we can understand that the LCM of 729,486,618,585,520 is 39045240.
