1 x 27, 3 x 9, 9 x 3, 27 x 1
The factor pairs for 77 are (1,77) and (7,11).
The factor pairs of 26 are the pairs of numbers that, when multiplied together, equal 26. The factor pairs of 26 are (1, 26) and (2, 13). These pairs represent the integer factors of 26.
The factor pairs of 51 are (1,51) and (17,3)
The difference is between factor pairs and distinct factors. With square numbers, one of the factor pairs will be the same number twice. When listing the distinct factors, that number is only listed once.
The factor pairs of 98 are (1,98), (2,49), and (7,14).
There are two factor pairs of 21: 21 = 1 x 21 21 = 3 x 7

Twenty only has three factor pairs. (20,1)(10,2)(5,4)
Three
there is no pair factors of the # seven. seven is a odd and composite #.

Since 7 is a factor of 21, it is automatically the GCF.
1 and 24 2 and 12 3 and 8 4 and 6
23 is a prime number, therefore the only two factors are 1 and 23.
Yes. Factor pairs are always repeated across pairs since factor pairs are certain kinds of pairs.
The only multiple of seven that is also a factor of seven is seven itself. This is because a factor of a number is a number that divides it evenly, and since seven divided by seven equals one, it fits this definition. Any other multiple of seven, such as fourteen or twenty-one, exceeds seven and thus cannot be a factor of it.
The factor pairs for 77 are (1,77) and (7,11).
