The GCF is 16.
It must be less than or equal to the smallest of the set of numbers whose GCF you are trying to obtain. So it must be less than or equal to 16. Furthermore, it is not 16 because 16 is not a factor of 42. Therefore, it must be less than 16.
3 6 and 9 would work but there are infinitely many solutions.
16
16
16, 32 and 48
The GCF of the given three numbers is 1
4 would be the GCF of those three numbers.
The GCF is 16.
16 doesn't have a GCF. You need at least two numbers to find one of those. If you're asking what three numbers equal 16, there are an infinite number of possibilities. If you're asking what three numbers have a GCF of 16, 16, 32 and 48 is one answer.
A set of numbers can only have one GCF. 6, 12 and 18 have a GCF of 6. 16, 32 and 48 have a GCF of 16. 25, 50 and 75 have a GCF of 25. The GCF of 6, 16 and 25 is 1.
There are three positive numbers that can have a GCF of 16 with 48. They are 16, 32 and 64.
16 32 and 48 have a GCF of 16.
16, 32 and 48 have a GCF of 16. Whether you added or multiplied to get them doesn't make much difference.
The GCF of 16 and 32 is 16.
gcf (greatest common factor) is usually calculated for two (or more) numbers, not for a single number.
9, 18 and 27 are three numbers that have a GCF of 9
