Hi, does anyone know if there's a "greatest common number" function? My teacher said most programs for example write gcd(7788,1386)=66.

But when I try here, it says gcd is an unknown function. Is there another way to write it?

gcd(7788,1386)=66 is correct. I don't know if this calculator does "gcd" and "lcm". You can try "WolframAlpha" and it should give you the answer.

I can't find "gcd" on this calculator. I think the best you can do here is to use the "factor" function:

factor(7788) gives 2^{2}*3*11*59

factor(1386) gives 2*3^{2}*7*11

Take the highest power of each prime that is common to both and multiply them together.

Here that is: 2*3*11 → 66
