Question
Find the $H.C.F$ of the following numbers using prime factorization method: $84,98$
✓
Answer
$84$ and $98$
Prime factorization of $84 = 2 \times 2 \times 3 \times 7$
Prime factorization of $98 = 2 \times 7 \times 7$
Therefore, $HCF = 2 \times 7 = 14$
Prime factorization of $84 = 2 \times 2 \times 3 \times 7$
Prime factorization of $98 = 2 \times 7 \times 7$
Therefore, $HCF = 2 \times 7 = 14$
