What is the greatest common factor of 62 and 72?

Answer 1

in order to find the GCF of two numbers follow these rules. multiply half of the numbers by 3 so inthis case it would be 31x3=93 and 36x3=108. then add 100 to both of them which brings them up to 193 and 208. After that subtract the sq root of each number (if there are decimals round to the nearest whole number) which now makes it 193-14=179 and 208-14=194. then multiply those numbers by 2. so right now each number is at 358 & 388. then add 26 to the lower number so right now the numbers are at 384 and 388. then subtract 384 from 388 (388-384). now you end up with four which is the GCF of 62 and 72. this method really does work. it's the easiest way to do it.
