How to Find the Factors of 2019?

To find the factors of 2019, we will have to find the list of numbers that would divide 2019 without leaving any remainder.

• 2019/3 = 673; therefore, 3 is a factor of 2019 and 673 is also a factor of 2019.
• 2019/2019 = 1; therefore, 2019 is a factor of 2019 and 1 is also a factor of 2019.

Similarly we can find other factors. Hence, the factors of 2019 are 1, 3, 673, 2019.

The number 2019 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 2019. The first step is to divide the number 2019 with the smallest prime factor, here it is 3. We keep dividing until it gives a non-zero remainder.

• 2019 ÷ 3 = 673

Further dividing 673 by 3 gives a non-zero remainder. So we stop the process and continue dividing the number 673 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 2019 can be written as 3¹ × 673¹ where 3, 673 are prime.

Pair factors of 2019 are the pairs of numbers that when multiplied give the product 2019. The factors of 2019 in pairs are:

• 1 × 2019 = (1, 2019)
• 3 × 673 = (3, 673)

Negative pair factors of 2019 are:

• -1 × -2019 = (-1, -2019)
• -3 × -673 = (-3, -673)

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