GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(394, 178) = 35066
GCD(394, 178) = ( 394 x 178 ) / 35066
= 394 / 178
= 394
Step2:
LCM(2, 688) = 688
GCD(2, 688) = ( 2 x 688 ) / 688
= 2 / 688
= 2
Step3:
LCM(2, 991) = 1982
GCD(2, 991) = ( 2 x 991 ) / 1982
= 2 / 991
= 2
So, Greatest Common Divisor of 394, 178, 688, 991 is 1
