Explanation

If we divide ‘68927’ by ‘93’ then we get:
\left(68927\div93\right)
\rightarrow 741 as a quotient and 14 as a remainder.
Here, 741 is the quotient and the next number of 741 is 742 .
If we multiply the divisor (93) to the next number of the quotient (742) then we get:
\left(93\times742\right)
\rightarrow 69006
Now, if we subtract 68927 from 69006 then we get the least number.
So, the least number is =\left(69006-68927\right)
\rightarrow 79
\therefore 79 is the least number.
Ans: To make 68927 exactly divisible by 93, the least number that must be added is 79.

Another Way

If we divide ‘68927’ by ‘93’ then we get:
\left(68927\div93\right)
\rightarrow 741 as a quotient and 14 as a remainder.
Now, if we subtract the remainder (14) form the divisor (93) , then we get:
\left(93-14\right)
\rightarrow 79
So, 79 is the least number which must be added.
Ans: To make 68927 exactly divisible by 93, the least number that must be added is 79.
