To find the HCF, you first have to express both numbers as the product of their prime factors:
15 = 3x5
20 = 2x2x5
The next step is to identify any common prime factors. In this case both numbers have a 5 as a prime factor. Therefore the HCF of 15 and 20 is 5.
The Highest Common Factor (HCF) of 15 and 20 is the largest positive integer that divides both 15 and 20 without leaving a remainder. To find the HCF, you can list the factors of each number and determine the largest factor they have in common. The factors of 15 are 1, 3, 5, and 15, while the factors of 20 are 1, 2, 4, 5, 10, and 20. The largest factor they have in common is 5, so the HCF of 15 and 20 is 5.
