Given numbers are 216,180,960
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 216,180,960 is 8640.
Find LCM of 216,180,960 with Prime Factorization
| 2 | 216, 180, 960 |
| 2 | 108, 90, 480 |
| 2 | 54, 45, 240 |
| 3 | 27, 45, 120 |
| 3 | 9, 15, 40 |
| 5 | 3, 5, 40 |
| 3, 1, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 3 x 1 x 8 = 8640
Therefore, the lowest common multiple of 216,180,960 is 8640.
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.
216 x 180 x 960 = 37324800
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.
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
12 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 216,180,960, is 12.
Now, the common factors can be found like this.
216:2x 2x 2x 3x 3x 3
180:2x 2x 3x 3x 5
960:2x 2x 2x 2x 2x 2x 3x 5
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 3x 3x 5 = 360
Therefore, the value for common factors is 360.
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 = 37324800/(12x360)
LCM = 37324800/4320
LCM = 8640
Thus, we can understand that the LCM of 216,180,960 is 8640.
