Answer 1

Answer:

1

Step-by-step explanation:

to check the divisibilty of any no. by 3 we can simply add the digits of that no. if the resulting sum is divisible by 3 then the given no. is also divisible by 3.

as given, 70356722

sum of digits = 7+0+3+5+6+7+2+2= 32

We can see that if add 1 in this sum this will completely divisible by 3 means we will add 1 to the given no. to make it divisible by 3.
