The LCM of 202,726,485,221,121 is 7859447310.
Find LCM of 202,726,485,221,121 with Prime Factorization
| 2 | 202, 726, 485, 221, 121 |
| 11 | 101, 363, 485, 221, 121 |
| 11 | 101, 33, 485, 221, 11 |
| 101, 3, 485, 221, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 11 x 101 x 3 x 485 x 221 x 1 = 7859447310
Therefore, the lowest common multiple of 202,726,485,221,121 is 7859447310.
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.
202 x 726 x 485 x 221 x 121 = 1901986249020
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.
202 : 1, 2, 101, 202
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
485 : 1, 5, 97, 485
221 : 1, 13, 17, 221
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 202,726,485,221,121, is 1.
Now, the common factors can be found like this.
202:2x 101
726:2x 3x 11x 11
485:5x 97
221:13x 17
121:11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11 = 242
Therefore, the value for common factors is 242.
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 = 1901986249020/(1x242)
LCM = 1901986249020/242
LCM = 7859447310
Thus, we can understand that the LCM of 202,726,485,221,121 is 7859447310.
