Question
Find the $H.C.F$ of the following numbers using prime factorization method: $144,198$
✓
Answer
$144$ and $198$
Prime factorization of $144 = 2 \times 2 \times 2 \times 3 \times 3$
Prime factorization of $198 = 2 \times 3 \times 3 \times 11$
Therefore, $HCF = 2 \times 2 \times 3 = 18$
Prime factorization of $144 = 2 \times 2 \times 2 \times 3 \times 3$
Prime factorization of $198 = 2 \times 3 \times 3 \times 11$
Therefore, $HCF = 2 \times 2 \times 3 = 18$
