Given numbers are 245, 346, 428, 397

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

Apply this formula for all numbers.

Step1:

LCM(245, 346) = 84770

GCD(245, 346) = ( 245 x 346 ) / 84770

= 245 / 346

= 245

Step2:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

Step3:

LCM(1, 397) = 397

GCD(1, 397) = ( 1 x 397 ) / 397

= 1 / 397

= 1

So, Greatest Common Divisor of 245, 346, 428, 397 is 1
