Given numbers are 425, 675, 991, 309

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

Apply this formula for all numbers.

Step1:

LCM(425, 675) = 11475

GCD(425, 675) = ( 425 x 675 ) / 11475

= 425 / 675

= 425

Step2:

LCM(25, 991) = 24775

GCD(25, 991) = ( 25 x 991 ) / 24775

= 25 / 991

= 25

Step3:

LCM(1, 309) = 309

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

= 1 / 309

= 1

So, Greatest Common Divisor of 425, 675, 991, 309 is 1
