1, 2 and 4
Numerators and denominators are just numbers. List the factors of each and circle the numbers that appear on both lists. These are common factors.
Write the factors of the first number in the left circle. Write the factors of the second number in the right circle. Write the numbers that are the same in each individual circle in the space where they intersect.
Example: What are the common prime factors of 120 and 252?Find the prime factorization of each number by breaking it down into the lowest possible numbers that can be multiplied together to make the original number.120 = 2x60 = 2x2x30 = 2x2x2x15 = 2x2x2x3x5252 = 2x126 = 2x2x63 = 2x2x3x21 = 2x2x3x3x7Notice that there are 2 2's and a 3 in each factorization: the common prime factors are 2, 2, and 3.
Please tell us your set of numbers.
The common factor is 1.
When two or more numbers each have one or more of the same factors, these factors are called common factors. A single number does not have common factors.
Just 1.

1 and 3
'Relatively Prime' simply means that two numbers have no common factors except 1 between each other. For example, two prime numbers would have no common factors between them. i.e., look at 3 and 10. There are no common factors between these 2 numbers.
The factors of 33 are 1,3,11,33 The factors of 55 are 1,5,11,55 Hence common factors are 1, & 11. as these two numbers appear in each list of factors.
Okay. Give us a pair of numbers.
