The numbers are: 12 and 72
LCM is 72 and GCF is 6..
the lcm for 60 and 72 is 360.
72 and 40
9 & 24
You need at least two numbers to find a GCF or an LCM and the LCM of those numbers can never be less than the GCF. 12 and 360 have a GCF of 12 and an LCM of 360. So do 60 and 72.
If you have two numbers m and n and their gcd (or gcf), g then their LCM = m*n/g so LCM = 72*252/36 = 2*252 = 504.
Gcf = 72 lcm = 432
You need at least two numbers to find either of those.
24 and 36
6 and 72, respectively.
The GCF is 4. The LCM is 72.
