Given numbers are 204,957,285,721,145
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 204,957,285,721,145 is 4457380620.
Find LCM of 204,957,285,721,145 with Prime Factorization
| 3 | 204, 957, 285, 721, 145 |
| 5 | 68, 319, 95, 721, 145 |
| 29 | 68, 319, 19, 721, 29 |
| 68, 11, 19, 721, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 29 x 68 x 11 x 19 x 721 x 1 = 4457380620
Therefore, the lowest common multiple of 204,957,285,721,145 is 4457380620.
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.
204 x 957 x 285 x 721 x 145 = 5816881709100
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.
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
957 : 1, 3, 11, 29, 33, 87, 319, 957
285 : 1, 3, 5, 15, 19, 57, 95, 285
721 : 1, 7, 103, 721
145 : 1, 5, 29, 145
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 204,957,285,721,145, is 1.
Now, the common factors can be found like this.
204:2x 2x 3x 17
957:3x 11x 29
285:3x 5x 19
721:7x 103
145:5x 29
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 29 = 1305
Therefore, the value for common factors is 1305.
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 = 5816881709100/(1x1305)
LCM = 5816881709100/1305
LCM = 4457380620
Thus, we can understand that the LCM of 204,957,285,721,145 is 4457380620.
