Given numbers are 247, 977, 204, 428

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

Apply this formula for all numbers.

Step1:

LCM(247, 977) = 241319

GCD(247, 977) = ( 247 x 977 ) / 241319

= 247 / 977

= 247

Step2:

LCM(1, 204) = 204

GCD(1, 204) = ( 1 x 204 ) / 204

= 1 / 204

= 1

Step3:

LCM(1, 428) = 428

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

= 1 / 428

= 1

So, Greatest Common Divisor of 247, 977, 204, 428 is 1
