(21,1)(7,3) (42,1)(21,2)(14,3)(7,6) Since 21 is a factor of 42, all the factors of 21 will be included in the factor pairs of 42.
The factor pairs of 210 are: 1 and 210, 2 and 105, 3 and 70, 5 and 42, 6 and 35, 7 and 30, 10 and 21, and 14 and 15. The factor pairs of 63 are: 1 and 63, 3 and 21, and 7 and 9.
No, 42 is a multiple of 3. 3 is a factor of 42.
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.

(21,1)(7,3) (42,1)(21,2)(14,3)(7,6) Since 21 is a factor of 42, all the factors of 21 will be included in the factor pairs of 42.
There are 4 factor pairs of 42.42 = 1 x 4242 = 2 x 2142 = 3 x 1442 = 6 x 7
Factor pairs of 84 are: 2 x 42, 3 x 28, 4 x 21, 6 x 84, 7 x 12
42 = 1 x 4242 = 2 x 2142 = 3 x 1442 = 6 x 7
The factor pairs of 210 are: 1 and 210 2 and 105 3 and 70 5 and 42 6 and 35 7 and 30 10 and 21 14 and 15
The Greatest Common Factor (GCF) is: 6
The factor pairs of 126 are 1 x 126, 2 x 63, 3 x 42, 6 x 21, 7 x 18, and 9 x 14
Yes. Factor pairs are always repeated across pairs since factor pairs are certain kinds of pairs.
