Given numbers are 394, 178, 688, 991

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
