Find LCM of 378,256,916,325,405 with Prime Factorization
| 2 | 378, 256, 916, 325, 405 |
| 2 | 189, 128, 458, 325, 405 |
| 3 | 189, 64, 229, 325, 405 |
| 3 | 63, 64, 229, 325, 135 |
| 3 | 21, 64, 229, 325, 45 |
| 5 | 7, 64, 229, 325, 15 |
| 7, 64, 229, 65, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 5 x 7 x 64 x 229 x 65 x 3 = 10802937600
Therefore, the lowest common multiple of 378,256,916,325,405 is 10802937600.
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.
378 x 256 x 916 x 325 x 405 = 11667172608000
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
916 : 1, 2, 4, 229, 458, 916
325 : 1, 5, 13, 25, 65, 325
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,256,916,325,405, is 1.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
256:2x 2x 2x 2x 2x 2x 2x 2
916:2x 2x 229
325:5x 5x 13
405:3x 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 3x 3x 3x 5 = 1080
Therefore, the value for common factors is 1080.
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 = 11667172608000/(1x1080)
LCM = 11667172608000/1080
LCM = 10802937600
Thus, we can understand that the LCM of 378,256,916,325,405 is 10802937600.
