Given numbers are 309, 831, 121, 412

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

Apply this formula for all numbers.

Step1:

LCM(309, 831) = 85593

GCD(309, 831) = ( 309 x 831 ) / 85593

= 309 / 831

= 309

Step2:

LCM(3, 121) = 363

GCD(3, 121) = ( 3 x 121 ) / 363

= 3 / 121

= 3

Step3:

LCM(1, 412) = 412

GCD(1, 412) = ( 1 x 412 ) / 412

= 1 / 412

= 1

So, Greatest Common Divisor of 309, 831, 121, 412 is 1
