Find LCM of 856,284,672,721,243 with Prime Factorization
| 2 | 856, 284, 672, 721, 243 |
| 2 | 428, 142, 336, 721, 243 |
| 2 | 214, 71, 168, 721, 243 |
| 3 | 107, 71, 84, 721, 243 |
| 7 | 107, 71, 28, 721, 81 |
| 107, 71, 4, 103, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 107 x 71 x 4 x 103 x 81 = 42592550112
Therefore, the lowest common multiple of 856,284,672,721,243 is 42592550112.
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.
856 x 284 x 672 x 721 x 243 = 28622193675264
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
284 : 1, 2, 4, 71, 142, 284
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
721 : 1, 7, 103, 721
243 : 1, 3, 9, 27, 81, 243
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,284,672,721,243, is 1.
Now, the common factors can be found like this.
856:2x 2x 2x 107
284:2x 2x 71
672:2x 2x 2x 2x 2x 3x 7
721:7x 103
243:3x 3x 3x 3x 3
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 2x 3x 7 = 672
Therefore, the value for common factors is 672.
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 = 28622193675264/(1x672)
LCM = 28622193675264/672
LCM = 42592550112
Thus, we can understand that the LCM of 856,284,672,721,243 is 42592550112.
