GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 238) = 77112
GCD(648, 238) = ( 648 x 238 ) / 77112
= 648 / 238
= 648
Step2:
LCM(2, 726) = 726
GCD(2, 726) = ( 2 x 726 ) / 726
= 2 / 726
= 2
Step3:
LCM(2, 591) = 1182
GCD(2, 591) = ( 2 x 591 ) / 1182
= 2 / 591
= 2
So, Greatest Common Divisor of 648, 238, 726, 591 is 1
