Write a set of three numbers that have a GCF of 16 what producer did you use to find your answer

Do you just find a number that goes to 16. For example I did 4 times 4 = 16 and and seance some thing goes to 4 and by the way there is 2 fourths and I múltiples it by 2 and I got 2 to the power of 4 becouse there is 4 "two's"

If that makes sense.
