Find LCM of 985,720,522,185,904 with Prime Factorization
| 2 | 985, 720, 522, 185, 904 |
| 2 | 985, 360, 261, 185, 452 |
| 2 | 985, 180, 261, 185, 226 |
| 3 | 985, 90, 261, 185, 113 |
| 3 | 985, 30, 87, 185, 113 |
| 5 | 985, 10, 29, 185, 113 |
| 197, 2, 29, 37, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 197 x 2 x 29 x 37 x 113 = 17197958160
Therefore, the lowest common multiple of 985,720,522,185,904 is 17197958160.
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.
985 x 720 x 522 x 185 x 904 = 61912649376000
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.
985 : 1, 5, 197, 985
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522
185 : 1, 5, 37, 185
904 : 1, 2, 4, 8, 113, 226, 452, 904
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,720,522,185,904, is 1.
Now, the common factors can be found like this.
985:5x 197
720:2x 2x 2x 2x 3x 3x 5
522:2x 3x 3x 29
185:5x 37
904:2x 2x 2x 113
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 2x 3x 3x 5x 5 = 3600
Therefore, the value for common factors is 3600.
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 = 61912649376000/(1x3600)
LCM = 61912649376000/3600
LCM = 17197958160
Thus, we can understand that the LCM of 985,720,522,185,904 is 17197958160.
