The LCM for any pair of natural numbers can be as big as their product.
No, it cannot be smaller than the largest of the set of numbers.
The LCM can be any positive integer.
Not normally
It's never less than the largest number.
No.
No, it's never greater than the smallest number.
A square number
False
Because there are many examples where that isn't so. The GCF of 36 and 24 is 12. The GCF of 151 and 149 is 1.
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.
No.
No.
No.
No. The LCM of 4 and 6 is 12.
The LCM is never less than the greatest number in the set. The LCM of 4 and 9 is 36.
No. At most, it can be equal to the smaller 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.
31
Not at all. For example: gcf(101, 102) = 1 gcf(40, 80) = 40
No, it's never greater than the smallest number.
