Question

Ab313ab is divisible by 12 then the smallest value of a b where a,b > 0 3

Answer 1

If it is Divisible by 3 and 4 Both, Then it is Divisible by 12

Answer 2

Answer:

4631346

Step-by-step explanation:

for divisibility by 12 the number mus be divisible by 4 and 3

for divisible by 4 last two digit is divisble by 4

then a*b= 4y

then both a and be are even.

so for divisible by 3 sum of all the digit will be divisble by 3

then a+b+3+1+3+a+b= 3x

⇒2a+2b+7=3x

by substituting min value a=4 and b= 6 it will divisible by 3

so number is 4631346
