GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(722, 784) = 283024
GCD(722, 784) = ( 722 x 784 ) / 283024
= 722 / 784
= 722
Step2:
LCM(2, 866) = 866
GCD(2, 866) = ( 2 x 866 ) / 866
= 2 / 866
= 2
Step3:
LCM(2, 646) = 646
GCD(2, 646) = ( 2 x 646 ) / 646
= 2 / 646
= 2
So, Greatest Common Divisor of 722, 784, 866, 646 is 2
