Factors of 441 by Prime Factorization
Factors of 35 by prime factorization are given by using the following steps:
 Step 1: Write the pair of factors, which on multiplication gives 441
 441 can be factored as a product of 21 and 21
 Step 2: 21 is not a prime number and can be factored in 3 × 7.
 3 and 7 are both prime numbers hence they cannot be factored further.
 Step 3: As per the criterion,441 can thereby be written as 441 = 21 × 21 = 3 × 7 × 3 × 7
Hence, the prime factors of 441 can be written as 441 = 3^{2} × 7^{2}
Factors of 441 in Pairs
Pair factors of the number 441 are the two whole numbers that multiply to get the original number. Pair factors could be either positive or negative but not a fraction or a decimal number.
 Positive factors of 441:(1, 441), (3, 147 ), ( 7, 63 ), ( 9, 49), ( 21, 21), (49, 9 ), (63, 7), (147, 3), (441, 1)
 Negative factors of 441: ( 1, 441), (3, 147 ), (7, 63), (9, 49), (21, 21), (49, 9), (63, 7), (147, 3), (441, 1)
Tips and Tricks:
 1 is the smallest factor of every number. Hence, it is a factor of 441
 3 is a factor of 441 because the sum of all the digits of 441 is 9 which is divisible by 3. Hence, 3 is one of its factors.
 441 is divisible by 3 and 7, hence 21 is one of its factors.

Factors of 441 Solved Examples

Example 1:Jessie's school has 441 students. If there are 21 classrooms in the entire school. Help her calculate how many students can sit in each classroom?
Solution:
Jessie's school has 441 students. There are 21 classrooms in the entire school.
To calculate the number of students in each classroom Jessie has to divide 441 by 21, (441 ÷ 21 = 21 ). She found that 21 students can sit in each classroom.

Example 2: Ashton went to a cinema hall having 441 chairs. If there were 9 rows in the hall, help Ashton calculate how many seats are there in each row?
Solution:
There were 441 chairs in the cinema hall. Ashton saw there were 9 rows in the hall.
To calculate the number of seats in each row he will divide 441 by 9 as given below. (441 ÷ 9 = 49 ). There will be 49 seats in each row.
