Which of the following is coprime?
Determine the co-prime.
Co-prime numbers or relatively prime numbers are those numbers that have their HCF (Highest Common Factor) as .
Calculate the value for the given points:
For point A)
HCF is .so it is co-prime.
For point B)
HCF is so, it is not co-prime.
For point C)
HCF is so,it is co-prime.
For point D)
HCF is so it is not a co-prime.
Hence, the correct option is “Option A and Option C”.
