HCF of 3 and 15 is the largest possible number which divides 3 and 15 without leaving any remainder. The methods to compute the HCF of 3, 15 are explained here.
Example: Find the HCF of 30 and 42.Solution: We will list the factors of 30 and 42. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30 and the factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. Clearly, 1, 2, 3, and 6 are the common factors of 30 and 42...
evaluate the hcf of 30 and 75 as we can note that the mentioned prime factors, on the left side, divide all the numbers exactly. so, they all are common prime factors. we have no common prime factor for the numbers remaining at the bottom. so, hcf = 3 × 5 = 15. example 2: ...

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 0.Is the answer correct? If not, what is the correct HCF?
15 = 3 × 5 18 = 2 3 3 Lastly, we can see that 3 is the only factor that 15 and 18 have in common. 15 =3× 5 18 = 233 This means that3is the Highest Common Factor of 15 and 18 orHCF (15, 18) = 3. Example 2: Using a Table ...
