Which one of the given numbers is completely divisible by 45? Choose the correct choice from the following.
A) 202860  B) 165642  C) 112330  D) 112333  E) None of these
We know that 45 = 9 × 5 where 9 and 5 are co-prime numbers. Also 9 and 5 are   factors of 45. Hence   if a number is divisible by 5 and 9, the number will be divisible by their product 45 also.   If a number is not divisible by 5 or 9, it is not divisible by 45   You must learn Divisibility Rules to say whether a given number is divisible by another number   Answer is A   without actually performing the division. Please go through divisibility rules before proceeding   further.   112330 is divisible by 5 but not divisible by 9 =&gt; 112330 is not divisible by 45   202860 is divisible by 5 and 9 =&gt; 202860 is divisible by 45   165642 is not divisible by 5 and 9 =&gt; 165642 is not divisible by 45
