Find the greatest common factor of 270 and 360. (Give the answer in the numerical form in the top box and in exponential form by filling in the boxes for exponents.)

Answer 1

270 = 2 * 3^3 * 5
360 = 2^3 * 3^2 * 5

Now pick the factors with the highest power of each prime, common to both numbers:

GCF = 2 * 3^2 * 5 = 90
