What are Factors of 2646?

Factors of 2646 are pairs of those numbers whose products result in 2646. These factors are either prime numbers or composite numbers.

How to Find the Factors of 2646?

To find the factors of 2646, we will have to find the list of numbers that would divide 2646 without leaving any remainder.

2646/294 = 9; therefore, 294 is a factor of 2646 and 9 is also a factor of 2646.
2646/378 = 7; therefore, 378 is a factor of 2646 and 7 is also a factor of 2646.

Similarly we can find other factors. Hence, the factors of 2646 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 49, 54, 63, 98, 126, 147, 189, 294, 378, 441, 882, 1323, 2646.

Factors of 2646 by Prime Factorization

The number 2646 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 2646. The first step is to divide the number 2646 with the smallest prime factor, here it is 2. We keep dividing until it gives a non-zero remainder.

2646 ÷ 2 = 1323

Further dividing 1323 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 1323 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 2646 can be written as 2¹ × 3³ × 7² where 2, 3, 7 are prime.

Factors of 2646 in Pairs

Pair factors of 2646 are the pairs of numbers that when multiplied give the product 2646. The factors of 2646 in pairs are:

1 × 2646 = (1, 2646)
2 × 1323 = (2, 1323)
3 × 882 = (3, 882)
6 × 441 = (6, 441)
7 × 378 = (7, 378)
9 × 294 = (9, 294)
14 × 189 = (14, 189)
18 × 147 = (18, 147)
21 × 126 = (21, 126)
27 × 98 = (27, 98)
42 × 63 = (42, 63)
49 × 54 = (49, 54)

Negative pair factors of 2646 are:

-1 × -2646 = (-1, -2646)
-2 × -1323 = (-2, -1323)
-3 × -882 = (-3, -882)
-6 × -441 = (-6, -441)
-7 × -378 = (-7, -378)
-9 × -294 = (-9, -294)
-14 × -189 = (-14, -189)
-18 × -147 = (-18, -147)
-21 × -126 = (-21, -126)
-27 × -98 = (-27, -98)
-42 × -63 = (-42, -63)
-49 × -54 = (-49, -54)

NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.

Factors of 2646 Solved Examples

Example 1: How many factors are there for 2646?

Solution:

The factors of 2646 are too many, therefore if we can find the prime factorization of 2646, then the total number of factors can be calculated using the formula shown below.
If the prime factorization of the number is a^x × b^y × c^z 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 2646 = 2¹ × 3³ × 7²
Therefore, the total number of factors are (1 + 1) × (3 + 1) × (2 + 1) = 2 × 4 × 3 = 24
Example 2: Find the Least Common Multiple (LCM) and Greatest Common Divisor (GCD) of 2646 and 571.

Solution:

The factors of 2646 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 49, 54, 63, 98, 126, 147, 189, 294, 378, 441, 882, 1323, 2646 and factors of 571 are 1, 571.

Therefore, the Least Common Multiple (LCM) of 2646 and 571 is 1510866 and Greatest Common Divisor (GCD) of 2646 and 571 is 1.
Example 3: Find if 3, 14, 18, 21, 42, 126, 344 and 882 are factors of 2646.

Solution:

When we divide 2646 by 344 it leaves a remainder. Therefore, the number 344 is not a factor of 2646. All numbers except 344 are factors of 2646.
Example 4: Find the product of all the prime factors of 2646.

Solution:

Since, the prime factors of 2646 are 2, 3, 7. Therefore, the product of prime factors = 2 × 3 × 7 = 42.
