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

Apply this formula for all numbers.

Step1:

LCM(245, 969) = 237405

GCD(245, 969) = ( 245 x 969 ) / 237405

= 245 / 969

= 245

Step2:

LCM(1, 897) = 897

GCD(1, 897) = ( 1 x 897 ) / 897

= 1 / 897

= 1

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 245, 969, 897, 243 is 1
