Detailed Solution

We have been given two numbers 875 and 1859.
Factors of 875 are 1, 5, 7, 25, 35, 125, 175, 875.
Similarly, the factors of 1859 are 1, 11, 13, 143, 169, and 1859.
The HCF of 875 and 1859 is 1.
We know, co-prime numbers are those numbers that do not have any common factor other than 1.
Therefore, our statement is false.
875 and 1859 are co-primes.
Hence, option 2 is correct.
