Since their GCF is 7, they must both be multiples of 7. Since their LCM is 28, they must both be factors of 28. The only numbers that are both factors of 28 and multiples of 7 are 7, 14, and 28. It cannot be 7 and 14, because the LCM of 7 and 14 is 14. It cannot be 14 and 28, because their GCF is 14. Therefore, it must be 7 and 28.
The factors of 7 are:
1, 7
The factors of 28 are:
1, 2, 4, 7, 14, 28
The common factors are:
1, 7
The Greatest Common Factor:
GCF = 7
There are infinitely many possible answers.
Then HCF(28p, 28q) = 28
where p and q are any two coprime numbers - that is numbers with no common factor between them. They need not be primes themselves. For example 4 and 15.
Two numbers that have seven as their greatest common factor are fourteen and twenty-one.
There are four number pairs that have an LCM of 8. None of them have a GCF of 7. We will not be able to find two whole numbers that satisfy those conditions.
7 is a Prime number. Thus, if 7 is also a factor of 28, then the GCF must be 7. If 7 is not a factor of 28, then the GCF must be 1.
7 is a factor of 28, so the GCF is 7.

Greatest Common Factor is GCF
The greatest common divisor is another name for the greatest common factor (GCF) and refers to the largest number that will divide into two or more numbers evenly with no remainder.
In that case, the smaller number is a factor of the larger one. The larger one is a multiple of the smaller one.
There is no acronym and so there is no such name.
The greatest common multiple is an infinite amount and not very practical for problem solving.
Two Numbers That Have The Greatest Common Factor Of Eight Are: 16 and 56
The greatest common factor for the numbers 3 and 37 is 1.
coprime

Greatest Common Factor is GCF
The greatest common divisor is another name for the greatest common factor (GCF) and refers to the largest number that will divide into two or more numbers evenly with no remainder.
5 and 10 5 and 15 5 and 20
200,205, 10
In that case, the smaller number is a factor of the larger one. The larger one is a multiple of the smaller one.
I thick it is 27 and 81
All numbers with a least common multiple, have that multiple as a factor.
27 and 81 are a possibility. Also numbers like 5 and 10, 20 and 40.
