Find LCM of 172,551,836,942,687 with Prime Factorization
| 2 | 172, 551, 836, 942, 687 |
| 2 | 86, 551, 418, 471, 687 |
| 3 | 43, 551, 209, 471, 687 |
| 19 | 43, 551, 209, 157, 229 |
| 43, 29, 11, 157, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 43 x 29 x 11 x 157 x 229 = 112442144628
Therefore, the lowest common multiple of 172,551,836,942,687 is 112442144628.
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.
172 x 551 x 836 x 942 x 687 = 51273617950368
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.
172 : 1, 2, 4, 43, 86, 172
551 : 1, 19, 29, 551
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
942 : 1, 2, 3, 6, 157, 314, 471, 942
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,551,836,942,687, is 1.
Now, the common factors can be found like this.
172:2x 2x 43
551:19x 29
836:2x 2x 11x 19
942:2x 3x 157
687:3x 229
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 19 = 456
Therefore, the value for common factors is 456.
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 = 51273617950368/(1x456)
LCM = 51273617950368/456
LCM = 112442144628
Thus, we can understand that the LCM of 172,551,836,942,687 is 112442144628.
