How do you connect all the factor pair of 21 and 42?
(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.
What pair of numbers is relatively prime 10 and 21 12 and 54 15 and 27 21 and 39?
I suggest factoring each pair of numbers, and checking whether they have, or don't have, common factors. A pair of numbers is said to be "relatively prime" if they have no common factors (their greatest common factor is 1). For larger numbers, Euclid's algorithm could be used, but for such small numbers, factoring is probably faster.
