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 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.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers. The greatest common factor of 12 and 27 is 3
Oh honey, the least common multiple of 12, 18, and 27 is 108. It's like finding the perfect outfit that fits everyone in the group - a rare gem, but not impossible. So go ahead and flaunt that LCM like it's the latest fashion trend.
