Given numbers are 309, 249, 136, 869

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

Apply this formula for all numbers.

Step1:

LCM(309, 249) = 25647

GCD(309, 249) = ( 309 x 249 ) / 25647

= 309 / 249

= 309

Step2:

LCM(3, 136) = 408

GCD(3, 136) = ( 3 x 136 ) / 408

= 3 / 136

= 3

Step3:

LCM(1, 869) = 869

GCD(1, 869) = ( 1 x 869 ) / 869

= 1 / 869

= 1

So, Greatest Common Divisor of 309, 249, 136, 869 is 1
