Question
Find the $H.C.F$ of the numbers: $36, 84.$
✓
Answer
Factors of $36$ are $1,2,3,4,6,9,12,18$ and $36.$
Factors of $84$ are $1,2,3,4,6,7,12,14,21,28,42$ and $84.$
$\therefore $ Common factors of $36$ and $84$ are $1, 2, 3, 4, 6$ and $12.$
Highest of these common factors is $12.$
$\therefore H.C.F.$ of $36$ and $84$ is $12.$
Factors of $84$ are $1,2,3,4,6,7,12,14,21,28,42$ and $84.$
$\therefore $ Common factors of $36$ and $84$ are $1, 2, 3, 4, 6$ and $12.$
Highest of these common factors is $12.$
$\therefore H.C.F.$ of $36$ and $84$ is $12.$
