Short answer: There are none.
There is neither a greatest common factor nor common factors of a single number, such as ??, 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.

What is the greatest common factor of 52 and 21?
The greatest common factor of 52 and 117 is 13.The common factors of 52 and 117 are 1 and 13.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 52 are 1, 2, 4, 13, 26, and 52.The factors of 117 are 1, 3, 9, 13, 39, and 117.The common factors are 1 and 13. Therefore, the greatest common factor is 13.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 52 are 2, 2, and 13.The prime factors of 117 are 3, 3, and 13.The prime factors in common are only 13, so the greatest common factor is 13.

What is the greatest common factor of 189 and 117?
The greatest common positive integer factor of 117 and 189 is 9.
What is the highest common factor of 117 and 130?
The greatest common factor of the numbers 117 and 130 is 13.
What numbers are factors of 117 and 42?
The greatest common denominator (gcd) of 42 and 117 is 3. So 3 is the only factor of both.
What is the least common multiple of 13 and 117?
Since 13 is a factor of 117, the least common multiple is 117. 13 x 9 = 117 117 x 1 = 117 Another way to determine the least common multiple is to multiply both numbers and divide by their greatest common factor. The greatest common factor of 13 and 117 is 13, so the least common multiple is 13 x 117 ÷ 13 = 117. Another way to determine the least common multiple is to determine the prime factors of the numbers and take the highest power of each prime factor. The prime factors of 13 are 13. The prime factors of 117 are 32 and 13. The highest power of 3 is 32 and the highest power of 13 is 131. Therefore, the least common multiple of 13 and 117 is 32 x 131 = 9 x 13 = 117.
