Factors of 197 by Prime Factorization

The number 197 is prime and therefore its factors are only the numbers 1 and 197 itself. Hence, it has only one prime factor that is the number itself, i.e. 197.

So, the prime factorization of 197 can be written as 197¹ where 197 is prime.

Factors of 197 in Pairs

Pair factors of 197 are the pairs of numbers that when multiplied give the product 197. The factors of 197 in pairs are:

1 × 197 = (1, 197)

Negative pair factors of 197 are:

-1 × -197 = (-1, -197)

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

Factors of 197 Solved Examples

Example 1: How many factors are there for 197?

Solution:

The factors of 197 are 1, 197. Therefore, 197 has 2 factors.
Example 2: Find the Lowest Common Multiple (LCM) and Highest Common Factor (HCF) of 197 and 63.

Solution:

The factors of 197 are 1, 197 and factors of 63 are 1, 3, 7, 9, 21, 63.

Therefore, the Lowest Common Multiple (LCM) of 197 and 63 is 12411 and Highest Common Factor (HCF) of 197 and 63 is 1.
Example 3: Find if 166 and 197 are factors of 197.

Solution:

When we divide 197 by 166 it leaves a remainder. Therefore, the number 166 is not a factor of 197. All numbers except 166 are factors of 197.
Example 4: Find the product of all the factors of 197.

Solution:

Since, the factors of 197 are 1, 197. Therefore, the product of factors = 1 × 197 = 197.
