It is: 42
405?
1 All of these numbers are primes. * * * * * That is the HCF or GCF. The LCD is 42
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.
It is 3 because 7 is a prime number and 6 can be divided into 3 by 2:)
LCD(7, 9, 2) = 126.
LCD(2, 3) = 6.
The least common denominator (LCD) is 1.
lcd(35, 60) = 420. 35 = 5 x 7 60 = 2^2 x 3 x 5 lcd = 2^2 x 3 x 5 x 7 = 420
