So when I see a question like this all I have to do is write out how I get that number.

OpenStudy (dayakar):

prime numbers begin from 2,3,5,7,11...so on

OpenStudy (dayakar):

35 is an odd number which is not divisible by 2

OpenStudy (dayakar):

sum of the digits in 35 = 3+5 = 8 is not divisible by 3 therefore ,35 is not divisible by 3

Yes, we can write EVERY number as a product of a bunch of prime numbers... Isn't that nice! ?

OpenStudy (dayakar):

unit digit in given number is 5,so it is divisible by 5. therefore ,35= 5*7' 5 and 7 both are primes
