Question
Find the common factors of $15$ and $25$
✓
Answer
$1 \times 15 = 15; 3 \times 5 = 15.$
Therefore Factors of $15$ are $1, 3, 5$ and $15.$
$1 \times 25 = 25; 5 \times 5 = 25.$
Therefore Factors of $25$ are $1, 5$ and $25.$
Hence, the common factors of $15$ and $25$ are $1$ and $5.$
Therefore Factors of $15$ are $1, 3, 5$ and $15.$
$1 \times 25 = 25; 5 \times 5 = 25.$
Therefore Factors of $25$ are $1, 5$ and $25.$
Hence, the common factors of $15$ and $25$ are $1$ and $5.$
