49 x 2 = 98 14 x 7 = 98 98 is the LCD
LCD(9, 28) = 252
LCD(28, 52) = 364
If that's 98 and 6, the LCD is 294. If that's 9, 8 and 6, the LCD is 72.

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.
