The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 51 and 175 is 1
The greatest common factor of 66 and 153 is 3.
The greatest common factor of 22 and 39 is 1.

Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 145, 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. The factors of 145 are 1, 5, 29, and 145. Examples: The common factors of 30 and 145 are 1 and 5; the greatest common factor is 5. The common factors of 145 and 149 are only 1; the greatest common factor is 1. The common factors of 145 and 174 are 1 and 29; the greatest common factor is 29.
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 51 and 175 is 1
The greatest common factor of 66 and 153 is 3.
The factors of 153 are 1, 3, 9, 17, 51, 153. For them to be common, they need to be compared to another set of factors.
Common factors of 102 and 153 are: 1, 3, 17, and 51.
There is not a greatest common factor of a single number, such as 306, because there cannot be a greatest 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. The factors of 306 are 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, and 306. The prime factors of 306 are 2, 3, 3, and 17. Examples: The greatest common factor of 27 and 306 is 9. The greatest common factor of 128 and 306 is 2. The greatest common factor of 306 and 765 is 153.
The greatest common factor of 22 and 39 is 1.
The GCF (Greatest Common Factor) of 1, 49, and 153 is 1, because 1 does not have any other factors.
181 is a prime and not a factor of 153. So the two are coprime and the gcd is 1. 1. 181 is a prime number and is only a multiples of 1 and 181. Since 153 is not a factor of 181, and all numbers are factors of 1, the greatest common divisor of the 2 numbers is 1
It is 9.

153 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 6 factors of 153 are 1, 3, 9, 17, 51, and 153.The factor pairs of 153 are 1 x 153, 3 x 51, and 9 x 17.The proper factors of 153 are 1, 3, 9, 17, and 51 or,if the definition you are using excludes 1, they are 3, 9, 17, and 51.The prime factors of 153 are 3, 3, and 17 Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.The 2 distinct prime factors (listing each prime factor only once) of 153 are 3 and 17.The prime factorization of 153 is 3 x 3 x 17 or, in index form (in other words, using exponents), 32 x 17.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 Greatest Common Divisor of 306, 765 is 153.
