Attempted by 101 students.
Show answer & explanation
Correct answer: 8
Step 1: Prime factorize 2014.
2014 = 2 × 1007 = 2 × 19 × 53, so the prime factorization is 2¹ × 19¹ × 53¹.
Step 2: Use the divisor-count formula. If n = pa x qb x rc …, the number of positive divisors is (a+1)(b+1)(c+1)…
Here the exponents are 1, 1, and 1, so the number of positive divisors is (1+1)(1+1)(1+1) = 2 × 2 × 2 = 8.
All positive divisors are:
1
2
19
38
53
106
1007
2014
Therefore, the number of distinct positive integral factors of 2014 is 8.
