Given numbers are 422, 860, 235, 720
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(422, 860) = 181460
GCD(422, 860) = ( 422 x 860 ) / 181460
= 422 / 860
= 422
Step2:
LCM(2, 235) = 470
GCD(2, 235) = ( 2 x 235 ) / 470
= 2 / 235
= 2
Step3:
LCM(1, 720) = 720
GCD(1, 720) = ( 1 x 720 ) / 720
= 1 / 720
= 1
So, Greatest Common Divisor of 422, 860, 235, 720 is 1
