Consecutive even numbers
The greatest common factor is the greatest number that fits evenly into all of the numbers. The least common multiple is the smallest number that is divisible by all of the numbers in the set. they are kind of like opposites of one another.
in what kind of problem?
The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question! The greatest factor of any number is itself.
Factors of 45: 1 3 5 9 15 45 Factors of 81: 1 3 927 81 Factors of 63: 1 3 7 9 21 63 The GCF of 45, 81, and 63 is 9
The least common factor is a term often mistakenly given to either the greatest common factor (GCF) or the least common multiple (LCM). This term is not often used because it does not describe a useful relationship between numbers. Since 1 evenly divides all integers, 1 is technically the least common factor for any set of integers.The smallest non-one common factor of 50 and 100 is 2.
An unnecessary one. 42 + 96 = 138
The only number with just one factor is 1.
The greatest common factor of 41 and 30 is 1. This is because 41 is a prime number, meaning it only has factors of 1 and itself. On the other hand, 30 can be factored into 2 x 3 x 5. Since there are no common factors between 41 and 30 other than 1, the greatest common factor is 1.
The GCF of 12, 18, and 27 is 3 The factors of 12 = 1x12, 2x6, 3x4 = 1, 2, 3, 4, 6, and 12 The factors of 18 = 1x18, 2x9, 3x6 = 1, 2, 3, 6, 9, and 18 The factors of 27 = 1x27, 3x9 = 1, 3, 9, and 27 The GCF is 3.
Those are the first five square numbers.
For this kind of question, I would suggest looking up a table of prime numbers. As an alternative, you can try to find factors for each of the numbers - if it has a factor, it is NOT a prime. For this range of numbers, testing for prime numbers up to 13 is appropriate. (If 17 is a factor of one of these numbers, the other factor is less than 17, so you would already have found it before you reach 17.)
Average. You'd have a one point lead. Prime numbers are better.
