Factors of 336 by Prime Factorization
When a composite number is expressed as the product of its prime factors, it is called as prime factorization. To get the prime factorization of 336, we use two methods:
 Method 1: Factor Tree Method
 Method 2: Upside Down Division Method
Method 1: Factor Tree Method
Factor tree of 336 is:
Method 2: Upside Division Method
We divide 336 by its smallest prime factor which is 2
336/2 = 168
168 is divided by its smallest prime factor and the quotient is obtained. This process is repeated till we get the quotient as 1. Thus, the prime factorization of 336 is:
Hence, the prime factors of 336 are 2, 3, and 7.
The prime factorization of 336 is 2^{4} × 3 × 7.
Factors of 336 in Pairs
The pair of numbers which on multiplication give 336 are the factor pairs of 336. Let's observe the following factors of 336 in pairs. The negative pair factors of 336 are obtained when the product of two negative numbers is taken (  ve ×  ve ) = +ve.
 Positive Pair Factors of 336 are: (1, 336), (2, 168), (3, 112), (4, 84), (6, 56), (7, 48), (8, 42), (12, 28), (14, 24), (16, 21)

Example 2: Can a rectangular box of length 16 inches and breadth 15 inches fit inside a rectangular box of area 336 square inches?
Solution:
The area of the given rectangular box of length 16 inches and breadth 15 inches is, area = 16 × 15 = 240 square inches while the area of other box is of 336 square inches.
The area of rectangular box of length 16 inches and breadth 15 inches is 240 square inches, which is less than the area of the other rectangular box of 336 square inches.
Hence, the rectangular box of length 16 inches and breadth 15 inches can fit inside the rectangular box of area 336 square inches.
