The LCM of 327,728,845,728 is 15473640.
Find LCM of 327,728,845,728 with Prime Factorization
| 2 | 327, 728, 845, 728 |
| 2 | 327, 364, 845, 364 |
| 2 | 327, 182, 845, 182 |
| 7 | 327, 91, 845, 91 |
| 13 | 327, 13, 845, 13 |
| 327, 1, 65, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 13 x 327 x 1 x 65 x 1 = 15473640
Therefore, the lowest common multiple of 327,728,845,728 is 15473640.
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.
327 x 728 x 845 x 728 = 146442528960
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.
327 : 1, 3, 109, 327
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
845 : 1, 5, 13, 65, 169, 845
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 327,728,845,728, is 1.
Now, the common factors can be found like this.
327:3x 109
728:2x 2x 2x 7x 13
845:5x 13x 13
728:2x 2x 2x 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.
2x 2x 2x 7x 13x 13 = 9464
Therefore, the value for common factors is 9464.
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 = 146442528960/(1x9464)
LCM = 146442528960/9464
LCM = 15473640
Thus, we can understand that the LCM of 327,728,845,728 is 15473640.
