The only single things that can be pairs are pants, scissors and glasses. The number 60 can be broken down into factor pairs, but is not a factor pair by itself.
36 does.
The only common whole number factor of 4 and 5 is 1.
1 has 1 factor.
The only number with a single factor is ' 1 '. Every other number has at least two factors: ' 1 ' and itself. A number with only those two factors and no others is called a "prime" number.
It is true.
The only common factor of 11 and 175 is 1. 11 is a prime number, the only two factors are 1 and 11. Every single number has a factor of 1. 11 does not divide into 175, so the only common factor is 1.
Only if enough copies of the single are sold.
A single number cannot have a common factor because "common" refers to factors that two or more numbers have in common. You have only one number.
"Common" means "same for both". There's no such thing as a "common" factor of only one single number.
A whole number greater than 1 whose only factors is itself and 1 is called a prime factor. 2, 3, 5, 7, and 11, are just a few of them.
The only common factor of 49 and 64 (whole number that goes into both of them evenly) is ' 1 '.
