Given numbers are 742, 791, 656, 720
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(742, 791) = 83846
GCD(742, 791) = ( 742 x 791 ) / 83846
= 742 / 791
= 742
Step2:
LCM(7, 656) = 4592
GCD(7, 656) = ( 7 x 656 ) / 4592
= 7 / 656
= 7
Step3:
LCM(1, 720) = 720
GCD(1, 720) = ( 1 x 720 ) / 720
= 1 / 720
= 1
So, Greatest Common Divisor of 742, 791, 656, 720 is 1
