Find LCM of 189,836,231,820,361 with Prime Factorization
| 2 | 189, 836, 231, 820, 361 |
| 2 | 189, 418, 231, 410, 361 |
| 3 | 189, 209, 231, 205, 361 |
| 7 | 63, 209, 77, 205, 361 |
| 11 | 9, 209, 11, 205, 361 |
| 19 | 9, 19, 1, 205, 361 |
| 9, 1, 1, 205, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 19 x 9 x 1 x 1 x 205 x 19 = 615425580
Therefore, the lowest common multiple of 189,836,231,820,361 is 615425580.
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.
189 x 836 x 231 x 820 x 361 = 10804411482480
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
231 : 1, 3, 7, 11, 21, 33, 77, 231
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
361 : 1, 19, 361
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,836,231,820,361, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
836:2x 2x 11x 19
231:3x 7x 11
820:2x 2x 5x 41
361:19x 19
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 3x 7x 11x 19 = 17556
Therefore, the value for common factors is 17556.
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 = 10804411482480/(1x17556)
LCM = 10804411482480/17556
LCM = 615425580
Thus, we can understand that the LCM of 189,836,231,820,361 is 615425580.
