Lcd = 1 Lcm = 112
The LCD of any two (or more) of positive integers is 1
The LCD is 36
20
Assuming you mean the LCM (Least Common Denominator of 2 fractions is the LCM of the denominators, which for 7/1 and 16/1 is 1), the answer is 112.
Lcd = 1 Lcm = 112
21
60
28
1 All of these numbers are primes. * * * * * That is the HCF or GCF. The LCD is 42
The LCD of any two (or more) of positive integers is 1
7 is prime, and 15 is not a multiple of it, so the answer is 1. ■
LCD(7, 4) = 28
lcd(7, 97) = 679.
LCD of 7 and 37 is 259.
LCD(7, 77) = 77
LCD(63, 7) = 63.
