Question

Find the least number to be added to $477682$ so that the result is exactly divisible by $598$.

Answer 1

Dividend = divisor $\times$ quotient + remainder

$477682=598\times 798+478$

Least number = divisor - remainder

= 598-478

= 120

Adding 120 to 477682

$\therefore 120+477682=477802$

Now, $\frac{477802}{598}=799,$ thus least number = 120
