198 is the greatest three-digit even number that has no factor equal to 4.
Yes, if that number is a factor of the other.
The GCF can be equal to the smaller number if the smaller number is a factor of the larger one. The GCF can be equal to both numbers if they are the same number. The GCF of 10 and 10 is 10.
998
4 is not a factor of 998
No. In order for something to be a factor of a number, it has to be less than or equal to the number.
Always equal to or less than the smaller number, yes.
If one number is divisible by another (in this case, 15 is divisible by 5), then the least common multiple is equal to the larger of the numbers (15), and the greatest common factor is equal to the smaller of the numbers (5).If one number is divisible by another (in this case, 15 is divisible by 5), then the least common multiple is equal to the larger of the numbers (15), and the greatest common factor is equal to the smaller of the numbers (5).If one number is divisible by another (in this case, 15 is divisible by 5), then the least common multiple is equal to the larger of the numbers (15), and the greatest common factor is equal to the smaller of the numbers (5).If one number is divisible by another (in this case, 15 is divisible by 5), then the least common multiple is equal to the larger of the numbers (15), and the greatest common factor is equal to the smaller of the numbers (5).
When they have a factor in common greater than one.
A single number cannot have a greatest common factor because "common" refers to factors that two or more numbers have in common. You have only one number.
Yes, if you're comparing a number to itself.
No. At most, it can be equal to the smaller number.
If the numerator was a factor of the denominator.
