To find whether the number 141 is prime or composite.
Answer to Problem 31E
The number is composite.
Explanation of Solution
Given Information: Number 141.
Formula used: To check if the numbers is prime or composite ,find its factors. If its factors are more than 2(except 1 and the number itself), then the number is composite else prime.
Calculation:
To determine if 141 a prime number or a composite number, simply look at the factors for 141.
If the factors of 141 are only 141 and 1, then 141 is a prime number. Otherwise, 141 is a composite number.
The factors of 141 are as follows:
1, 3, 47 and 141
Therefore, since 141 is divisible by more than one and itself, the number is composite.
