No. When finding the greatest common factor of two numbers, the factors of each number must divide that number "evenly", which means that the quotient of that division must be an integer. If a "factor" of a number were larger than that number, the quotient would be less than 1, and so the "factor" wouldn't actually be a factor because it doesn't divide the number evenly. At the same time, one can "factor" 4 out of 2 and get 4*(1/2), but that isn't considered a factor in the usual sense.
Not at all. For example: gcf(101, 102) = 1 gcf(40, 80) = 40
When that number is a factor of the greater one.
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.
GCF - Greatest Common Factor (GCF is always smaller or equal to at least one of the numbers) LCM - Least Common Multiple (LCM is always greater or equal to at least one of the numbers)
5 or 10
The LCM will never be less than the GCF of a set of numbers.
No, the GCF of any two numbers can't get greater than the smaller of the two numbers.
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.
The LCM of two numbers will never be less than the GCF.
Not at all. For example: gcf(101, 102) = 1 gcf(40, 80) = 40
12, 24 and 120
No but it can be the same as the biggest number as for example the gcf of 30 and 15 is 30
The LCM of a set of numbers will never be less than the GCF.
The LCM of a set of numbers will never be less than the GCF.
You need at least two numbers to find a GCF.
When their GCF is greater than one.
When that number is a factor of the greater one.
