A number can't have a factor greater than itself, so the GCF of a pair of numbers can't ever be greater than the smaller number. The GCF of 9 and 18 is 9.
0.4
A prime number is an integer which is greater than one and which is evenly divisible only by one and itself. A pair of prime numbers consists of two such numbers.
The LCM is never less than the greatest number in the set. The LCM of 4 and 9 is 36.
The sum of any pair of prime numbers greater than 2 is an even number.
A number can't have a factor greater than itself, so the GCF of a pair of numbers can't ever be greater than the smaller number. The GCF of 9 and 18 is 9.
No, it's never greater than the smallest number.
No. At most, it can be equal to the smaller number.
No, it's never greater than the smallest number.
No.
No.
No.
I can't give you an example of when that happens because that doesn't ever happen. The GCF of a pair of numbers can't be larger than the smaller number.
No.
Not at all. For example: gcf(101, 102) = 1 gcf(40, 80) = 40
No. Although the greatest common denominator of a pair of numbers is infinite, the size of the numbers doesn't affect the GCF as much as the difference between them. The GCF of 100 and 102 is 2. The GCf of 33 and 66 is 33.
No. The LCM of 4 and 6 is 12.
