Hello, GoldenSimmer!
Try factoring the number.What two-digit numbers have a product of 6,789?
We have tried multiplying numerous numbers. . . . . quite possibly the WORST method!
We see that it is divisible by 3: .$\displaystyle 6789 \div 3 \:=\:2263$
Then we try dividing by consecutive primes (3, 5, 7, 11, 13, ...)
. . to determine other factors.
It takes a while, but we find that: .$\displaystyle 2263 \:=\:31 \times 73$
. . Hence: .$\displaystyle 6789 \:=\:3 \times 31 \times 73$
Therefore: .$\displaystyle 6789 \;=\;73 \times 93$
