Find LCM of 363,693,217,161,775 with Prime Factorization
| 3 | 363, 693, 217, 161, 775 |
| 7 | 121, 231, 217, 161, 775 |
| 11 | 121, 33, 31, 23, 775 |
| 31 | 11, 3, 31, 23, 775 |
| 11, 3, 1, 23, 25 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 31 x 11 x 3 x 1 x 23 x 25 = 135879975
Therefore, the lowest common multiple of 363,693,217,161,775 is 135879975.
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.
363 x 693 x 217 x 161 x 775 = 6811255506825
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.
363 : 1, 3, 11, 33, 121, 363
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
217 : 1, 7, 31, 217
161 : 1, 7, 23, 161
775 : 1, 5, 25, 31, 155, 775
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 363,693,217,161,775, is 1.
Now, the common factors can be found like this.
363:3x 11x 11
693:3x 3x 7x 11
217:7x 31
161:7x 23
775:5x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7x 11x 31 = 50127
Therefore, the value for common factors is 50127.
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 = 6811255506825/(1x50127)
LCM = 6811255506825/50127
LCM = 135879975
Thus, we can understand that the LCM of 363,693,217,161,775 is 135879975.
