Given numbers are 988, 798, 164, 991

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(988, 798) = 20748

GCD(988, 798) = ( 988 x 798 ) / 20748

= 988 / 798

= 988

Step2:

LCM(38, 164) = 3116

GCD(38, 164) = ( 38 x 164 ) / 3116

= 38 / 164

= 38

Step3:

LCM(2, 991) = 1982

GCD(2, 991) = ( 2 x 991 ) / 1982

= 2 / 991

= 2

So, Greatest Common Divisor of 988, 798, 164, 991 is 1
