Question
Find the $H.C.F$ of the following numbers using prime factorization method: $170, 238$
✓
Answer
$170$ and $238$
Prime factorization of $170 = 2 \times 5 \times 17$
Prime factorization of $238 = 2 \times 7 \times 17$
Therefore, $HCF = 2 \times 17 = 34$
Prime factorization of $170 = 2 \times 5 \times 17$
Prime factorization of $238 = 2 \times 7 \times 17$
Therefore, $HCF = 2 \times 17 = 34$
