1. Prime factorization of 262:
- 262 = 2 x 131
- The prime factors of 262 are 2 and 131.
2. Identifying the missing factor:
- To make 262 a perfect square, we need to find the missing factor that will complete the square.
- Since the prime factorization of 262 includes 2, we need another factor of 2 to make it a perfect square.
