Answer:
Some of the possible pairs are,
(7, 14), (21, 28), (28, 35), (42, 49), (63, 70).
Step-by-step explanation:
If two numbers have GCF( greatest common factor ) 7,
Then there are no common factor of these numbers other than 7,
∵ Multiples of 7 are,
7, 14, 21, 28, 35, 42, 49, 63, 70, .... so on,,,
Thus, some pairs which have GCF 7 are,
(7, 14), (21, 28), (28, 35), (42, 49), (63, 70).
