Given numbers are 191, 697, 81, 998

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

Apply this formula for all numbers.

Step1:

LCM(191, 697) = 133127

GCD(191, 697) = ( 191 x 697 ) / 133127

= 191 / 697

= 191

Step2:

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

= 1 / 81

= 1

Step3:

LCM(1, 998) = 998

GCD(1, 998) = ( 1 x 998 ) / 998

= 1 / 998

= 1

So, Greatest Common Divisor of 191, 697, 81, 998 is 1
