Find LCM of 997,909,945,745,997 with Prime Factorization
| 3 | 997, 909, 945, 745, 997 |
| 3 | 997, 303, 315, 745, 997 |
| 5 | 997, 101, 105, 745, 997 |
| 997 | 997, 101, 21, 149, 997 |
| 1, 101, 21, 149, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 997 x 1 x 101 x 21 x 149 x 1 = 14178641085
Therefore, the lowest common multiple of 997,909,945,745,997 is 14178641085.
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.
997 x 909 x 945 x 745 x 997 = 636124732278525
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.
997 : 1, 997
909 : 1, 3, 9, 101, 303, 909
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
745 : 1, 5, 149, 745
997 : 1, 997
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,909,945,745,997, is 1.
Now, the common factors can be found like this.
997:997
909:3x 3x 101
945:3x 3x 3x 5x 7
745:5x 149
997:997
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 997 = 44865
Therefore, the value for common factors is 44865.
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 = 636124732278525/(1x44865)
LCM = 636124732278525/44865
LCM = 14178641085
Thus, we can understand that the LCM of 997,909,945,745,997 is 14178641085.
