Find LCM of 117,729,243,987,546 with Prime Factorization
| 3 | 117, 729, 243, 987, 546 |
| 3 | 39, 243, 81, 329, 182 |
| 3 | 13, 27, 81, 329, 182 |
| 3 | 13, 9, 27, 329, 182 |
| 3 | 13, 3, 9, 329, 182 |
| 7 | 13, 1, 3, 329, 182 |
| 13 | 13, 1, 3, 47, 26 |
| 1, 1, 3, 47, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 3 x 3 x 7 x 13 x 1 x 1 x 3 x 47 x 2 = 6235866
Therefore, the lowest common multiple of 117,729,243,987,546 is 6235866.
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.
117 x 729 x 243 x 987 x 546 = 11169390093498
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.
117 : 1, 3, 9, 13, 39, 117
729 : 1, 3, 9, 27, 81, 243, 729
243 : 1, 3, 9, 27, 81, 243
987 : 1, 3, 7, 21, 47, 141, 329, 987
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 117,729,243,987,546, is 3.
Now, the common factors can be found like this.
117:3x 3x 13
729:3x 3x 3x 3x 3x 3
243:3x 3x 3x 3x 3
987:3x 7x 47
546:2x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3x 3x 3x 3x 7x 13 = 597051
Therefore, the value for common factors is 597051.
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 = 11169390093498/(3x597051)
LCM = 11169390093498/1791153
LCM = 6235866
Thus, we can understand that the LCM of 117,729,243,987,546 is 6235866.
