No. Zero is never a factor, except for maybe zero itself and that's a matter of definition that I don't know.
The greatest common factor is used to reduce fractions.
A single number cannot have a greatest common factor. A greatest common factor is used to compare two or more numbers.
A Greatest Common Factor (GCF) is used to compare two or more numbers. A single number cannot have a Greatest Common Factor.
The GCF is used to simplify fractions. The LCF is practically useless, since it is always 1.
When you want to reduce fractions.
There is not a greatest common factor of 56 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 56 are 1, 2, 4, 7, 8, 14, 28, and 56.The prime factors of 56 are 2, 2, 2, and 7.Examples:The greatest common factor of 16 and 56 is 8.The greatest common factor of 44 and 56 is 4.The greatest common factor of 56 and 63 is 7.You need at least two numbers to find a GCF.
You need at least two numbers to find a GCF. If that's 9 and 6, the GCF is 3.
You need at least two numbers to find a GCF. If that's 9 and 25, the GCF is 1.
There is not a greatest common factor of 70 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 factors of 70 are 1, 2, 5, 7, 10, 14, 35, and 70.You need at least two numbers to find a GCF.

To split things into smaller sections.
The least common factor is a term often mistakenly given to either the greatest common factor (GCF) or the least common multiple (LCM). This term is not often used because it does not describe a useful relationship between numbers. Since 1 evenly divides all integers, 1 is technically the least common factor for any set of integers.The smallest non-one common factor of 192 and 1296 is 2.
