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.
The LCD of 6 and 7 is 42
42
The LCD is 9.
42
49 x 2 = 98 14 x 7 = 98 98 is the LCD
42/49
42 and 49 are both divisible by 7. 42/49= 6/7
42
42 x 49 = 2058
