Find LCM of 261,405,244,856,135 with Prime Factorization
2 | 261, 405, 244, 856, 135 |
2 | 261, 405, 122, 428, 135 |
3 | 261, 405, 61, 214, 135 |
3 | 87, 45, 61, 214, 135 |
3 | 29, 15, 61, 214, 45 |
5 | 29, 5, 61, 214, 15 |
29, 1, 61, 214, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 5 x 29 x 1 x 61 x 214 x 3 = 613276920
Therefore, the lowest common multiple of 261,405,244,856,135 is 613276920.
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.
261 x 405 x 244 x 856 x 135 = 2980525831200
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.
261 : 1, 3, 9, 29, 87, 261
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
244 : 1, 2, 4, 61, 122, 244
856 : 1, 2, 4, 8, 107, 214, 428, 856
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 261,405,244,856,135, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
405:3x 3x 3x 3x 5
244:2x 2x 61
856:2x 2x 2x 107
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 3x 3x 3x 3x 3x 5 = 4860
Therefore, the value for common factors is 4860.
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 = 2980525831200/(1x4860)
LCM = 2980525831200/4860
LCM = 613276920
Thus, we can understand that the LCM of 261,405,244,856,135 is 613276920.
