Best Answer

There cannot be a least common factor of 27, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The least common factor would be the smallest common factor that all the numbers have, which would be 1.

The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 27 are 1, 3, 9, and 27. The common factors of 12 and 27 are 1 and 3. Therefore, the least common factor (the smallest common factor) is 1.

The least common factor of 45, 27, and 25 is 1. If you meant the least common multiple of those three numbers, then that would be 675. The factors of 25 are 1, 5, and 25. The factors of 27 are 1, 3, 9, and 27. The factors of 45 are 1, 3, 5, 9, 15, and 45. The only common factor is 1. Therefore, it is both the greatest common factor (the largest one) and the least common factor (the smallest one).

The factors of 81 are 1, 3, 9, 27, and 81. The factors of 243 are 1, 3, 9, 27, 81, and 243. The common factors of 81 and 243 are 1, 3, 9, 27, and 81. Therefore, the least common factor (the smallest common factor) is 1.

Since 27 is a factor of 54, and 27 cannot have a larger factor than itself, the greatest common factor of 27 and 54 is 27.

The least common factor is the smallest factor that two or more numbers have in common. Thus, the least common factor of two numbers is 1. The least common factor of 48 and 116 is 1.
