What least value should be given to *so that the number 8456 *4107 is divisible by 3?
Answer:-We should know the divisibility rule of 3.what does it say?.
Divisibility rule of 3 – Sum of the digits must be divisible by 3.
In this given number (8456 *4107) sum of the digits is
which is not divisible by 3.
so we can not put * as 0.
but we can take * as 1.
If we will put * as 1 the sum would be =8+4+5+6+1+4+1+0+7
which is divisible by 3.
Hence 1 is the least value that can give to * so that the number
