Given numbers are 197, 148, 981, 809

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

Apply this formula for all numbers.

Step1:

LCM(197, 148) = 29156

GCD(197, 148) = ( 197 x 148 ) / 29156

= 197 / 148

= 197

Step2:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

Step3:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1

So, Greatest Common Divisor of 197, 148, 981, 809 is 1
