Find the H.C.F. of $18$ and $48$ .

Open in App

Solution

As we know that Highest Common Factors are the highest factors of numbers that are common between the numbers.
Factors of $18 = 1, 2, 3, 6, 9, 18$
Factors of $48 = 1, 2, 3, 4, 6, 8, 12, 16, 24, 48$
Since common factors of $(18, 48) = 1, 2, 3, 6$
Hence, the H.C.F. of $18$ and $48$ is $6 .$
