Desmos has lcm, gcd, and mod. Type the function instead of listing factors by hand. gcd is the greatest common factor. Desmos access is in Desmos on the ACT.
Three functions, three jobs
lcm(12, 18) is 36. gcd(12, 18) is 6. mod(17, 5) is 2, the remainder. Percent arithmetic is a different keypad job, in percent calculations in Desmos.
Statistics functions are a separate list, in statistics functions. Fractions as answers are in fraction answers.
The bottom line
lcm, gcd, and mod are typed functions. Do not factor on scratch paper unless the numbers are tiny.
