Find LCM of 657,231,112,551,836 with Prime Factorization
| 2 | 657, 231, 112, 551, 836 |
| 2 | 657, 231, 56, 551, 418 |
| 3 | 657, 231, 28, 551, 209 |
| 7 | 219, 77, 28, 551, 209 |
| 11 | 219, 11, 4, 551, 209 |
| 19 | 219, 1, 4, 551, 19 |
| 219, 1, 4, 29, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 19 x 219 x 1 x 4 x 29 x 1 = 445992624
Therefore, the lowest common multiple of 657,231,112,551,836 is 445992624.
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.
657 x 231 x 112 x 551 x 836 = 7829846506944
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.
657 : 1, 3, 9, 73, 219, 657
231 : 1, 3, 7, 11, 21, 33, 77, 231
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
551 : 1, 19, 29, 551
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,231,112,551,836, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
231:3x 7x 11
112:2x 2x 2x 2x 7
551:19x 29
836:2x 2x 11x 19
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 7x 11x 19 = 17556
Therefore, the value for common factors is 17556.
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 = 7829846506944/(1x17556)
LCM = 7829846506944/17556
LCM = 445992624
Thus, we can understand that the LCM of 657,231,112,551,836 is 445992624.
