How do you find the greatest common factor when there are no common factors?
There is always a common factor. If there are no common prime factors, the GCF is 1.
Is the GCF of any two numbers always odd and why?
The GCF of any two odd numbers is always odd because odd numbers don't have any even factors. The GCF of any two even numbers is always even because even numbers are divisible by two and any common factors would have at least one two in common. The GCF of an even and an odd number is odd because odd numbers don't have any even factors.
What are the greatest common factors of 56 and 71?
The GCF of 56 and 71 is 1. Hint: If the larger number is a prime number (no factors except 1 and itself such as 71) then the GCF will always be 1.
Why are greatest common factors always even numbers?
They aren't. The GCF of 18 and 21 is 3.
What is the gfc of 48 and 88?
GCF is 8.48 factors 1,2,3,4,6,8,12,16,24,4888 factors 1,2,4,8,11,22,44,88
Are there any 2 even numbers that the GCF is an odd number?
No not always as for example the GCF of 7 and 21 is 7
Is the gcf of a odd number and an even number always even?
The GCF of an odd and even number is never even.
Why is the GCF of any odd numbers always odd?
The GCF of any set of odd numbers is odd because odd numbers don't have any even factors.
What is the gcf for 14 and 49?
Factors of 14=1,2,7,14 Factors of 49=1,7,49 GCF of 14 & 49=7
What is the GCF of 27 and 30?
The GCF is 3.3
What are the factors for the GCF 4?
The factors of 4 are 1, 2 and 4. You need another set of factors to find a GCF.
Why is the gcf of two prime numbers always 1?
Because they don't have any other factors in common.
