Yes.
You can tell right away just by looking at it that 177 is divisible by 3. It may also bedivisible by other numbers, but you don't need to know that. As soon as you know ofone other factor besides ' 1 ' and itself, you know a number is composite.

Both. It is a number and it is composite.
Composite number
If it is composite, you can not make a number prime.
Since the sum if its digits (1 + 7 + 7 = 15) is divisible by 3, the original number 177 is divisible by 3.Now we know that it has at least one factor in addition to '1' and itself, so it's not prime.
177 = 180 - 3 and 3 goes into 180 so not a prime (59 x 3 = 177)

515 is a composite number. NB Remember #1 ; Any number ending in an even number ( 0,2,4,6,8) is composite. #2 ; Any number ending in '0' or '5' is composite. #3 ; Any number whose digits sum to '9' is composite. e.g. 135 = 1 + 3 + 5 = 9 is a multiple of '9'. #4 ; You only need to divide by '3' or '7' to test for prime number. It the result is a whole number then it is NOT a prime. NNB Since the above number , 515, ands in ;5; then it is composite.
