Find LCM of 891,836,874,342 with Prime Factorization
| 2 | 891, 836, 874, 342 |
| 3 | 891, 418, 437, 171 |
| 3 | 297, 418, 437, 57 |
| 11 | 99, 418, 437, 19 |
| 19 | 9, 38, 437, 19 |
| 9, 2, 23, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 11 x 19 x 9 x 2 x 23 x 1 = 1557468
Therefore, the lowest common multiple of 891,836,874,342 is 1557468.
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.
891 x 836 x 874 x 342 = 222649395408
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
874 : 1, 2, 19, 23, 38, 46, 437, 874
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,836,874,342, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
836:2x 2x 11x 19
874:2x 19x 23
342:2x 3x 3x 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 3x 11x 19x 19 = 142956
Therefore, the value for common factors is 142956.
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 = 222649395408/(1x142956)
LCM = 222649395408/142956
LCM = 1557468
Thus, we can understand that the LCM of 891,836,874,342 is 1557468.
