No. The sum of its digits, 5 + 3 + 1, is divisible by 3, which means the number itself is also divisible by 3.
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
By the fact that it is a PRIME Number, it does NOT factorise, except for itself and '1'. They named prime numbers because they do factorise. NB Except for '2' all prime numbers are odd numbers. However, NOT all odd numbers are prime number. Odd numbers ending in 1,3,7,& 9. can be prime numbers. Odd numbers ending in '5' are NOT prime number So to test for a prime number. If it is EVEN , ending in 0,2,4,6,8 , it is NOT a Prime Number. It is ends in '5' it is NOT a prime Number. If the digits sum to '9' it is NOT a Prime Number. e.g. 531 ; 5 + 3 + 1 = 9 So 531/ 9 = 59 So it is NOT a Prime number. Then divide the given number by '3' or '7', if there isa remainder then it is a prime number. So 1253 Try '3' = 417 remainder '2' Try '7' =179 So 1253 is NOT a prime number.

Prime factorization for 531: 1x3x3x59 As you can see 531 is divisible by 3 & 9
531 is composite
531 is not a prime number. Other than itself and one, it is also divisible by 3, 9, 59, and 177.
531 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
The prime factorization of 531 is: 32 x 59
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 531 is composite.
531 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1, 2, and 0. 1, 2, and 0 have a different name.A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 531 is composite.
It is: 3*3*59 = 531
531 = 3 * 3 * 59
3 x 3 x 59 = 531, making it composite.
