GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 114) = 82194
GCD(721, 114) = ( 721 x 114 ) / 82194
= 721 / 114
= 721
Step2:
LCM(1, 897) = 897
GCD(1, 897) = ( 1 x 897 ) / 897
= 1 / 897
= 1
Step3:
LCM(1, 684) = 684
GCD(1, 684) = ( 1 x 684 ) / 684
= 1 / 684
= 1
So, Greatest Common Divisor of 721, 114, 897, 684 is 1
