Given numbers are 485,209,217,418,189
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 485,209,217,418,189 is 1187795070.
Find LCM of 485,209,217,418,189 with Prime Factorization
| 7 | 485, 209, 217, 418, 189 |
| 11 | 485, 209, 31, 418, 27 |
| 19 | 485, 19, 31, 38, 27 |
| 485, 1, 31, 2, 27 |
Multiply the prime numbers at the bottom and the left side.
7 x 11 x 19 x 485 x 1 x 31 x 2 x 27 = 1187795070
Therefore, the lowest common multiple of 485,209,217,418,189 is 1187795070.
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.
485 x 209 x 217 x 418 x 189 = 1737744187410
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.
485 : 1, 5, 97, 485
209 : 1, 11, 19, 209
217 : 1, 7, 31, 217
418 : 1, 2, 11, 19, 22, 38, 209, 418
189 : 1, 3, 7, 9, 21, 27, 63, 189
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 485,209,217,418,189, is 1.
Now, the common factors can be found like this.
485:5x 97
209:11x 19
217:7x 31
418:2x 11x 19
189:3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 11x 19 = 1463
Therefore, the value for common factors is 1463.
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 = 1737744187410/(1x1463)
LCM = 1737744187410/1463
LCM = 1187795070
Thus, we can understand that the LCM of 485,209,217,418,189 is 1187795070.
