Answer:

stay home stay safe

Step-by-step explanation:

If the highest common factor (HCF) of two numbers is equal to 1, then they are called co-prime or relatively prime. HCF of co-prime numbers 4 and 15 was found as follows by factorisation: 4 = 2 × 2 and 15 = 3 × 5; Since there is no common prime factor, so HCF of 4 and 15 is 1.
