Find LCM of 172,688,897,693,874 with Prime Factorization
| 2 | 172, 688, 897, 693, 874 |
| 2 | 86, 344, 897, 693, 437 |
| 3 | 43, 172, 897, 693, 437 |
| 23 | 43, 172, 299, 231, 437 |
| 43 | 43, 172, 13, 231, 19 |
| 1, 4, 13, 231, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 43 x 1 x 4 x 13 x 231 x 19 = 2708609904
Therefore, the lowest common multiple of 172,688,897,693,874 is 2708609904.
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 688 x 897 x 693 x 874 = 64291564681344
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
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
897 : 1, 3, 13, 23, 39, 69, 299, 897
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
874 : 1, 2, 19, 23, 38, 46, 437, 874
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,688,897,693,874, is 1.
Now, the common factors can be found like this.
172:2x 2x 43
688:2x 2x 2x 2x 43
897:3x 13x 23
693:3x 3x 7x 11
874:2x 19x 23
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 23x 43 = 23736
Therefore, the value for common factors is 23736.
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 = 64291564681344/(1x23736)
LCM = 64291564681344/23736
LCM = 2708609904
Thus, we can understand that the LCM of 172,688,897,693,874 is 2708609904.
