A prime number is a number that is divisible only by 1 and itself; it has no other factors. A composite number is a number that is divisible by more than 2 numbers. The factors of 253 are 1, 11, 23, and 253. Therefore, 253 is a composite number.

The number 253 is composite. Why? 11*23 = 253. That means 253 has more factors than one and itself. Any number which has more factors than one and itself is composite, not prime.

Prime factorization of 253 is: 11 x 23

11 × 23

The GCF of 138, 253, and 805 is 23.The prime factorization of 138 is 2*3*23The prime factorization of 253 is 11*23The prime factorization of 805 is 5*7*23Thus, the GCF of 138, 253, and 805 is 23.
