Given numbers are 427, 602, 857, 309

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

Apply this formula for all numbers.

Step1:

LCM(427, 602) = 36722

GCD(427, 602) = ( 427 x 602 ) / 36722

= 427 / 602

= 427

Step2:

LCM(7, 857) = 5999

GCD(7, 857) = ( 7 x 857 ) / 5999

= 7 / 857

= 7

Step3:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

So, Greatest Common Divisor of 427, 602, 857, 309 is 1
