GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(558, 991) = 552978
GCD(558, 991) = ( 558 x 991 ) / 552978
= 558 / 991
= 558
Step2:
LCM(1, 930) = 930
GCD(1, 930) = ( 1 x 930 ) / 930
= 1 / 930
= 1
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 558, 991, 930, 921 is 1
