Find LCM of 120,997,836,873,882 with Prime Factorization
| 2 | 120, 997, 836, 873, 882 |
| 2 | 60, 997, 418, 873, 441 |
| 3 | 30, 997, 209, 873, 441 |
| 3 | 10, 997, 209, 291, 147 |
| 10, 997, 209, 97, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 10 x 997 x 209 x 97 x 49 = 356542872840
Therefore, the lowest common multiple of 120,997,836,873,882 is 356542872840.
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.
120 x 997 x 836 x 873 x 882 = 77013260533440
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.
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
997 : 1, 997
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
873 : 1, 3, 9, 97, 291, 873
882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,997,836,873,882, is 1.
Now, the common factors can be found like this.
120:2x 2x 2x 3x 5
997:997
836:2x 2x 11x 19
873:3x 3x 97
882:2x 3x 3x 7x 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 = 77013260533440/(1x216)
LCM = 77013260533440/216
LCM = 356542872840
Thus, we can understand that the LCM of 120,997,836,873,882 is 356542872840.
