There cannot be a greatest common factor (GCF) of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.

A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common. 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 45 are 1, 3, 5, 9, 15, and 45. The factors of 77 are 1, 7, 11, and 77. The only common factor is 1. Therefore, the greatest common factor is 1.

Same as the greatest common factor of 225 and 45 (where 45 is the remainder of the division of the two numbers).

Short answer: There are none.There is neither a greatest common factor nor common factors of a single number, such as 45, 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.Examples:The common factors of 18 and 45 are 1, 3, and 9; the greatest common factor is 9.The common factors of 25 and 45 are 1 and 5; the greatest common factor is 5.
