Answer 2

start dividing by 2, then 3, then 5, then 7. etc until you cant divide no more.

Answer 3

Since the sum of the given digits = 9 i.e. ( 6+2+1=9)
so this number is divisible by 3
start dividing it by 3

Answer 4

621 = 3 *207
= 3 *3* 69
= 3 *3* 3* 23
since 23 is the prime number, hence it can not be further factorised.
Therefore factor od 621 is 3 *3* 3* 23
