The gcf of two numbers is 850 neither number is divisible by the other what is the smallest these two numbers can be?

Began by dividing 850 by 1, then 2, then 3, and so on, and I made a list of the whole numbers.

They were 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, and 850

By inspection, the two smallest numbers which when multiplied together yielded 850 were 25 and 34.

Idrk but i think u should figure out the n dia n then the units it will make it way more easier
