# A large

A large gear will be used to turn a smaller gear. The large gear will make 75 revolutions per minute. The smaller gear must make 384 revolutions per minute. Find the smallest number of teeth each gear could have. [Hint: Use either GCF or LCM. ]

Correct result:

a =  128
b =  25

#### Solution:

$b=75\mathrm{/}k=75\mathrm{/}3=25$
