Given numbers are 484,644,120,135
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 484,644,120,135 is 21039480.
Find LCM of 484,644,120,135 with Prime Factorization
| 2 | 484, 644, 120, 135 |
| 2 | 242, 322, 60, 135 |
| 3 | 121, 161, 30, 135 |
| 5 | 121, 161, 10, 45 |
| 121, 161, 2, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 121 x 161 x 2 x 9 = 21039480
Therefore, the lowest common multiple of 484,644,120,135 is 21039480.
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.
484 x 644 x 120 x 135 = 5049475200
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.
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
135 : 1, 3, 5, 9, 15, 27, 45, 135
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 484,644,120,135, is 1.
Now, the common factors can be found like this.
484:2x 2x 11x 11
644:2x 2x 7x 23
120:2x 2x 2x 3x 5
135:3x 3x 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 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 5049475200/(1x240)
LCM = 5049475200/240
LCM = 21039480
Thus, we can understand that the LCM of 484,644,120,135 is 21039480.
