Answer:
Greatest common factor is 21
Step-by-step explanation:
Factors of 42 : 1,2,3,6,7,14,21,42
Factors of 63:1,3,7,9,21,63
So Greatest Common Factor is 21
Yi did one mistake when he was giving the factors of 63 he missed out two values which are 3 and 21 so due to this he missed the greatest common factor which was 21.
