Find LCM of 486,221,378,231,675 with Prime Factorization
| 2 | 486, 221, 378, 231, 675 |
| 3 | 243, 221, 189, 231, 675 |
| 3 | 81, 221, 63, 77, 225 |
| 3 | 27, 221, 21, 77, 75 |
| 7 | 9, 221, 7, 77, 25 |
| 9, 221, 1, 11, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 9 x 221 x 1 x 11 x 25 = 206756550
Therefore, the lowest common multiple of 486,221,378,231,675 is 206756550.
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.
486 x 221 x 378 x 231 x 675 = 6330472047900
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.
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
221 : 1, 13, 17, 221
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
231 : 1, 3, 7, 11, 21, 33, 77, 231
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 486,221,378,231,675, is 1.
Now, the common factors can be found like this.
486:2x 3x 3x 3x 3x 3
221:13x 17
378:2x 3x 3x 3x 7
231:3x 7x 11
675:3x 3x 3x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 3x 3x 3x 7 = 30618
Therefore, the value for common factors is 30618.
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 = 6330472047900/(1x30618)
LCM = 6330472047900/30618
LCM = 206756550
Thus, we can understand that the LCM of 486,221,378,231,675 is 206756550.
