What Are Factors of 380?
Numbers that divide the given number exactly without any remainder are termed as factors . According to the definition of factors, the factors of 380 are 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380. So, 380 is a composite number as it has more factors other than 1 and itself. There are total 12 factors of 380.
How To Calculate Factors of 380?
Using methods like divisibility test, prime factorization, and the upsidedown division method we can calculate the factors of 380. In the division method, we see which numbers divide 380 exactly without a remainder. In prime factorization, we express 380 as a product of its prime factors.
Let us calculate factors of 380 using follwoing two simple methods:
 Factors of 380 by division method
 Factors of 380 by prime factorization method
Factors of 380 By Division Method
Let us divide whole numbers with 380 and see which number divides 380 exactly without leaving a remainder.
 380 ÷ 1 = 380
 380 ÷ 2 = 190
 380 ÷ 4 = 95
 380 ÷ 5 = 76
 380 ÷ 10 = 38
 380 ÷ 19 = 20
According to division method we have 0 as a remainder for all the numbers. The divisor and the obtained quotient are the factors of 380. These are the numbers which exactly divides the 380 without leaving any remainder. Hence, the factors of 380 are 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380.
Prime Factorization of 380
As discussed above prime factorization of a number is a product of prime factors of that number. Let us try find the prime factorization of 380 with the help of following steps:
 Using divisibility rules, find the smallest factor of 380.
 Divide 380 by 2 = 380 ÷ 2 = 190.
 Now find the prime factors of the quotient obtained.
 190 is a quotient.
 Now, 190 ÷ 2 = 95.
 95 is a next quotient.
 90 ÷ 5 = 19
 Now divide 19 ÷ 19 = 1. Here we can stop the process.
 In the steps we observed that we used all the prime numbers to solve the upsidedown division. Hence all these numbers are prime factors of 380.
 Prime factorization of 380 is 2 × 2 × 5 × 19.
 2, 5, and 19 are prime factors of 380.
Hence, the factors of 380 are 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190 and 380.

Factors of 380 In Pairs
The pair of numbers that give 380 when multiplied with each other is called the pair factors of 380.
 380 = 1 × 380
 380 = 2 × 190
 380 = 4 × 95
 380 = 5 × 76
 380 = 10 × 38
 380 = 19 × 20
 Therefore, the factor pairs of 380 are (1, 380), (2, 190), (4, 95), (5, 76), (10, 38), and (19, 20).
 Since the product of two negative numbers is positive, i.e. () × () = (+).
 Hence, (1, 380), (2, 190), (4, 95), (5, 76), (10, 38), and (19, 20). are negative factor pairs of 380.
