Factors of 882 by Prime Factorization
- 882 ÷ 2 = 441
Further dividing 441 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 441 by the next smallest prime factor. We stop ultimately if the next prime factor doesn't exist or when we can't divide any further.
So, the prime factorization of 882 can be written as 21 × 32 × 72 where 2, 3, 7 are prime.
Factors of 882 in Pairs
Pair factors of 882 are the pairs of numbers that when multiplied give the product 882. The factors of 882 in pairs are:
- 1 × 882 = (1, 882)
- 2 × 441 = (2, 441)
- 3 × 294 = (3, 294)
- 6 × 147 = (6, 147)
- 7 × 126 = (7, 126)
- 9 × 98 = (9, 98)
- 14 × 63 = (14, 63)
- 18 × 49 = (18, 49)
- 21 × 42 = (21, 42)
Negative pair factors of 882 are:
- -1 × -882 = (-1, -882)
- -2 × -441 = (-2, -441)
- -3 × -294 = (-3, -294)
- -6 × -147 = (-6, -147)
- -7 × -126 = (-7, -126)
- -9 × -98 = (-9, -98)
- -14 × -63 = (-14, -63)
- -18 × -49 = (-18, -49)
- -21 × -42 = (-21, -42)
NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.

Example 1: How many factors are there for 882?
Solution:
The factors of 882 are too many, therefore if we can find the prime factorization of 882, then the total number of factors can be calculated using the formula shown below.
If the prime factorization of the number is ax × by × cz where a, b, c are prime, then the total number of factors can be given by (x + 1)(y + 1)(z + 1).
Prime Factorization of 882 = 21 × 32 × 72
Therefore, the total number of factors are (1 + 1) × (2 + 1) × (2 + 1) = 2 × 3 × 3 = 18 -
