You need to compare at least two numbers to find a GCF.
871 and 1742 have a GCF of 871.
871 and 1742 is one possibility.
871 and 871. If they need to be different, 871 and 1742.
871 and 871. If they need to be different, 871 and 1742.
871 and any multiple of 871
871 and 1742 is one possibility.
871 and 871. If they have to be different, 871 and 1742
Answer: None, it is impossible. No single number has a greatest common factor. A "common factor" is a factor that two or more numbers have in common. The "greatest common factor" is the largest factor that two or more numbers have in common.
There is neither a greatest common factor nor common factors of a single number, such as 871, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor.
Both numbers are not even. If they were, the GCF would be 1742 (871*2) i think it is 5 of the two rear numbers factor
I've seen variations of this question that say that the GCF of two numbers is 871. Choose 871 and any multiple of 871 or any two multiples of 871 that differ by 871.
1742 and 2613
