Question: 2 to the power p, 3 to power q, 5 to power r and 2 to power q, 3 to power r, 7 to power p Hi David,If you find the letters intimidating try some numbers for p, q and r first and then try it with p, q and r as unknowns. For example try p = 7, q = 8, and r = 9. The numbers are then
Since 7 < 8 the highest power of 2 that divides both numbers is 2^{7} Thus the greatest common divisor of 2^{7} x 3^{8} x 5^{9} and 2^{8} x 3^{9} x 5^{7}is Now can you see how to do it in general? Penny
