Question

Find the 3-digit number in which each of the three digits is a prime number;and the number is divisible by each of the three digits.with steps

Answer 1

prime digits are 2,3,5,7

if we take 3 then sum of the digits should be divisible by 3

and if we take 5 then at last it would be 5

So keep 5 at unit digit

now we have to make sum divisible by 3

So 5 + 2 + 3= 10 which is not divisible by 3

so now 5 + 3 +7= 15 which is divisible by 3

So let's check for 375 , it 's not divisible by 7

so interchange first two digits then 735 then it's divisible by 7

hence no is 735
