LCD(7, 9, 2) = 126.
lcm(7, 9) = 63 → equivalent fractions are: 3/7 = (3×9)/(7×9) = 27/63 2/9 = (2×7)/(9×7) = 14/63
9 = 3^2 15 = 3 x 5 21 = 3 x 7 lcm = 3^2 x 5 x 7 = 315

To find the least common denominator (LCD) of the numbers 98, 36, and 42, we first determine their prime factorizations: 98 = 2 × 7^2 36 = 2^2 × 3^2 42 = 2 × 3 × 7 The LCD is obtained by taking the highest power of each prime number present in the factorizations. This gives us: LCD = 2^2 × 3^2 × 7^2 = 4 × 9 × 49 = 1764. Thus, the LCD of 98, 36, and 42 is 1764.
