a three digit number,abc in which digits are prime numbers and it is divisible by a,b,c
Prime numbers 2 , 3 , 5 , 7
Total three digit Possible numbers = ⁴P₃ = 24
2 & 5 both can not be used together as number has to end with 2 or 5 to be divisivle
So possible case
Using digit 2 , 3 , 7 & 3 , 5 , 7
Case 1 : using 2 , 3 , 7
should end with 2
hence 372 & 732 are possible numbers
372 & 732 does not divided with 7
Case 3 : using 3 , 5 , 7
should end with 5
hence 375 & 735 are possible numbers
375 does not divided with 7
735 / 3 = 245
735 / 5 = 145
735/ 7 = 105
Hence 735 is a three digit number in which digits are prime numbers and it is divisible by 7 , 3 & 5
