Find LCM of 935,180,990,221 with Prime Factorization
| 2 | 935, 180, 990, 221 |
| 3 | 935, 90, 495, 221 |
| 3 | 935, 30, 165, 221 |
| 5 | 935, 10, 55, 221 |
| 11 | 187, 2, 11, 221 |
| 17 | 17, 2, 1, 221 |
| 1, 2, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 17 x 1 x 2 x 1 x 13 = 437580
Therefore, the lowest common multiple of 935,180,990,221 is 437580.
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.
935 x 180 x 990 x 221 = 36822357000
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.
935 : 1, 5, 11, 17, 55, 85, 187, 935
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 935,180,990,221, is 1.
Now, the common factors can be found like this.
935:5x 11x 17
180:2x 2x 3x 3x 5
990:2x 3x 3x 5x 11
221:13x 17
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 5x 5x 11x 17 = 84150
Therefore, the value for common factors is 84150.
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 = 36822357000/(1x84150)
LCM = 36822357000/84150
LCM = 437580
Thus, we can understand that the LCM of 935,180,990,221 is 437580.
