Given numbers are 209, 957, 242, 897

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

Apply this formula for all numbers.

Step1:

LCM(209, 957) = 18183

GCD(209, 957) = ( 209 x 957 ) / 18183

= 209 / 957

= 209

Step2:

LCM(11, 242) = 242

GCD(11, 242) = ( 11 x 242 ) / 242

= 11 / 242

= 11

Step3:

LCM(11, 897) = 9867

GCD(11, 897) = ( 11 x 897 ) / 9867

= 11 / 897

= 11

So, Greatest Common Divisor of 209, 957, 242, 897 is 1
