16 <h2>Factor Tree</h2>

15 <h2>Factor Tree</h2>

17 <p>The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows - Step 1: Firstly, 1640 is divided by 2 to get 820. Step 2: Now divide 820 by 2 to get 410. Step 3: Then divide 410 by 2 to get 205. Step 4: Divide 205 by 5 to get 41. Here, 41 is the smallest prime number that cannot be divided anymore. So, the prime factorization of 1640 is: 2³ × 5 × 41. Factor Pairs Two numbers that are multiplied to give a specific number are called factor pairs. Both positive and negative factors constitute factor pairs. Positive factor pairs of 1640: (1, 1640), (2, 820), (4, 410), (5, 328), (8, 205), (10, 164), (20, 82), and (41, 40). Negative factor pairs of 1640: (-1, -1640), (-2, -820), (-4, -410), (-5, -328), (-8, -205), (-10, -164), (-20, -82), and (-41, -40).</p>
