The LCM of 788,831,414,252 is 316281924.
Find LCM of 788,831,414,252 with Prime Factorization
| 2 | 788, 831, 414, 252 |
| 2 | 394, 831, 207, 126 |
| 3 | 197, 831, 207, 63 |
| 3 | 197, 277, 69, 21 |
| 197, 277, 23, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 197 x 277 x 23 x 7 = 316281924
Therefore, the lowest common multiple of 788,831,414,252 is 316281924.
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.
788 x 831 x 414 x 252 = 68316895584
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.
788 : 1, 2, 4, 197, 394, 788
831 : 1, 3, 277, 831
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,831,414,252, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
831:3x 277
414:2x 3x 3x 23
252:2x 2x 3x 3x 7
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 = 68316895584/(1x216)
LCM = 68316895584/216
LCM = 316281924
Thus, we can understand that the LCM of 788,831,414,252 is 316281924.
