Find LCM of 873,188,168,342 with Prime Factorization
| 2 | 873, 188, 168, 342 |
| 2 | 873, 94, 84, 171 |
| 3 | 873, 47, 42, 171 |
| 3 | 291, 47, 14, 57 |
| 97, 47, 14, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 97 x 47 x 14 x 19 = 43656984
Therefore, the lowest common multiple of 873,188,168,342 is 43656984.
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.
873 x 188 x 168 x 342 = 9429908544
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.
873 : 1, 3, 9, 97, 291, 873
188 : 1, 2, 4, 47, 94, 188
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
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 873,188,168,342, is 1.
Now, the common factors can be found like this.
873:3x 3x 97
188:2x 2x 47
168:2x 2x 2x 3x 7
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 2x 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 9429908544/(1x216)
LCM = 9429908544/216
LCM = 43656984
Thus, we can understand that the LCM of 873,188,168,342 is 43656984.
