According to "The Complete GMAT Arithmetic & Number Properties Course 2026: From Zero to Expert!", when dealing with a large composite number and asked to find its prime factorization, which of the following approaches is most conceptually sound for efficiency and accuracy in a timed test scenario?
Using a calculator to find the prime factors by trial division with a wide range of numbers.
Randomly selecting prime numbers and attempting to divide the composite number; if successful, repeat with the quotient.
Identifying obvious small prime factors (2, 3, 5) and then focusing on factoring the remaining quotient using increasingly larger primes, utilizing divisibility rules and known prime squares.
Systematically dividing by all prime numbers starting from 2 until the quotient is 1.

In the context of "The Complete GMAT Arithmetic & Number Properties Course 2026: From Zero to Expert!", what is the fundamental underlying principle that differentiates a "perfect number" from a "deficient number"?
The sum of all divisors (including the number itself) of a perfect number is twice the number, while for a deficient number, this sum is less than twice the number.
A perfect number is divisible by all prime numbers up to its square root, while a deficient number is not.
A perfect number has an even number of factors, whereas a deficient number has an odd number of factors.
The sum of a perfect number's proper divisors is equal to the number itself, whereas a deficient number's proper divisors sum to less than the number.

"The Complete GMAT Arithmetic & Number Properties Course 2026: From Zero to Expert!" emphasizes the importance of understanding the properties of remainders. If $N$ is an integer such that when $N$ is divided by 7, the remainder is 3, and when $N$ is divided by 5, the remainder is 2, what is the smallest positive integer value of $N$?
