Given numbers are 245, 196, 547, 421

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

Apply this formula for all numbers.

Step1:

LCM(245, 196) = 980

GCD(245, 196) = ( 245 x 196 ) / 980

= 245 / 196

= 245

Step2:

LCM(49, 547) = 26803

GCD(49, 547) = ( 49 x 547 ) / 26803

= 49 / 547

= 49

Step3:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

So, Greatest Common Divisor of 245, 196, 547, 421 is 1
