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.

531 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 6 factors of 531 are 1, 3, 9, 59, 177, and 531.The factor pairs of 531 are 1 x 531, 3 x 177, and 9 x 59.The proper factors of 531 are 1, 3, 9, 59, and 177 or,if the definition you are using excludes 1, they are 3, 9, 59, and 177.The prime factors of 531 are 3, 3, and 59. Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.The 2 distinct prime factors (listing each prime factor only once) of 531 are 3 and 59.The prime factorization of 531 is 3 x 3 x 59 or, in index form (in other words, using exponents), 32 x 59.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.1, 3, 9, 59, 177, 531
A factor can or cannot be a prime number Ex: 2 is the factor of all other even numbers its a prime number but 9 is a factor of 18 and its not a prime number A prime is a factor but a factor being a prime number varies
A prime number times a prime number is a composite number. Since prime numbers, except for 2, are odd numbers, a prime number times a prime number is usually an odd number. It will only be an even number if one of the prime numbers is 2. A prime number times a prime number will be a number with four factors unless both prime numbers are the same, in which case it will be a square number with only three factors.
If it is composite, you can not make a number prime.
It is divisible by 3 or 59 177/59=3

531 is not a prime number. Other than itself and one, it is also divisible by 3, 9, 59, and 177.
no
177 = 180 - 3 and 3 goes into 180 so not a prime (59 x 3 = 177)
As a product of its prime factors: 3*59 = 177
It is: 3 times 59 = 177
Because it has more than two factors
1,31, 15.5, 2, 7.75, 4 ..... but there are only two factors: 1 and 31 making it a prime number 177
177, using the '3' divisibility rule, 7 + 7 + 1 = 15, where 15 mod 3 = 0. Thus, 177 is divisible by 3. 177/3 = 59. 59 is a prime, thus the factors of 177 is:{1, 3, 59, 177}, the only ones that properly divide 177.
113 + 64 = 177
