Find LCM of 495,221,979,585 with Prime Factorization
| 3 | 495, 221, 979, 585 |
| 3 | 165, 221, 979, 195 |
| 5 | 55, 221, 979, 65 |
| 11 | 11, 221, 979, 13 |
| 13 | 1, 221, 89, 13 |
| 1, 17, 89, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 11 x 13 x 1 x 17 x 89 x 1 = 9736155
Therefore, the lowest common multiple of 495,221,979,585 is 9736155.
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.
495 x 221 x 979 x 585 = 62652157425
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.
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
221 : 1, 13, 17, 221
979 : 1, 11, 89, 979
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 495,221,979,585, is 1.
Now, the common factors can be found like this.
495:3x 3x 5x 11
221:13x 17
979:11x 89
585:3x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 11x 13 = 6435
Therefore, the value for common factors is 6435.
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 = 62652157425/(1x6435)
LCM = 62652157425/6435
LCM = 9736155
Thus, we can understand that the LCM of 495,221,979,585 is 9736155.
