You'd have to tell us the sets of numbers for us to answer that.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. Specific sets of numbers will have specific lists of common factors. The largest number on the list of common factors is the greatest common factor, or GCF. It is the largest number that will divide evenly with no remainder into a set of given numbers.
The least (meaning lowest) common factor of any set of whole numbers is always 1. The greatest common factor of any set of whole numbers will depend on the factors of the individual whole numbers in the set.

Co-prime numbers, relatively prime numbers and any set of prime numbers.
The greatest common factor, or GCF, is the largest positive integer that will divide evenly with no remainder into all the members of a given set of numbers. The least common multiple, or LCM, is the smallest positive integer that all the members of a given set of numbers will divide into evenly with no remainder. Factors go into numbers, numbers go into multiples.
You need at least two numbers to find a GCF.
Short answer: There are none.There is neither a greatest common factor nor common factors of a single number, such as 23, 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 23 and 25 are only 1; the greatest common factor is 1.The common factors of 23 and 69 are 1 and 23; the greatest common factor is 23.The common factors of 23 and 75 are only 1; the greatest common factor is 1.The factors of 23 are 1 and 23. For them to be common, they need to be compared to another set of factors.
No single number has those. To find something in common, at least two numbers need to be compared. In any set of numbers that includes 1, it is always both the greatest and least common factor of the set.
It is the lowest common number between to initila numbers.Ex.: GCF of 2,3 & 4 is 122: 2, 4, 6, 8, 10, 12, 14,16, 20...3: 3, 6, 9, 12, 15, 18, 21...4: 4, 8, 12, 16, 20...
The greatest common multiple of any set of numbers is infinite. The greatest common multiple of any set of numbers will never be one.
1 is the least common factor of all whole numbers, so there is nothing to choose for a least common factor. The Greatest Common Factor (GCF) of a set of two or more numbers is the largest factor that will divide into every number in the set without leaving any remainder. 1 is the least, or smallest, factor common to all whole numbers.
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. 3 is a factor of 9. 3 is a factor of 15. 3 is a common factor of 9 and 15.
