61 is a prime number. The only two factors of a prime number are 1 and itself.The two factors of 61 are 1 and 61. There are only two factors of a prime number.The only factor pair of 61 is 1 x 61. There is only one factor pair of a prime number.The proper factors of 61 are only 1 or,if the definition you are using excludes 1, there are none.The only prime factor of 61 is 61. There is only one prime factor of a prime number - itself.The distinct prime factor (listing each prime factor only once) of 61 is also 61.The prime factorization of 61 is 61. In some cases, to emphasize that it is prime, you might write the prime factorization as 1 x 61.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
427 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 4 factors of 427 are 1, 7, 61, and 427.The factor pairs of 427 are 1 x 427 and 7 x 61.The proper factors of 427 are 1, 7, and 61 or,if the definition you are using excludes 1, they are 7 and 61.The prime factors of 427 are 7 and 61.The 2 distinct prime factors (listing each prime factor only once) of 427 are 7 and 61.The prime factorization of 427 is 7 x 61.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
The factors of 82 are: 1, 2, 41, 82The factors of 122 are: 1, 2, 61, 122The common factors are: 1, 2The Greatest Common Factor (GCF) is: 2

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.

The factors of 82 are: 1, 2, 41, 82The factors of 122 are: 1, 2, 61, 122The common factors are: 1, 2The Greatest Common Factor (GCF) is: 2
1525 is a composite number. It has factors other than 1 and itself. It is not a prime number.The 6 factors of 1525 are 1, 5, 25, 61, 305 and 1525.The factor pairs of 1525 are 1 x 1525, 5 x 305 and 25 x 61.The proper factors of 1525 are 1, 5, 25, 61 and 305 or,if the definition you are using excludes 1, the proper factors are 5, 25, 61 and 305.The prime factors of 1525 are 5, 5 and 61.The distinct prime factors (listing each prime factor only once) of 1525 are 5 and 61.The prime factorization of 1525 is 5 x 5 x 61 or, in index form (in other words, using exponents), 52 x 61.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
61 is a prime number, meaning that its only factors are 1 and itself. So 1 and 61.
