Given numbers are 775, 520, 981, 309

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

Apply this formula for all numbers.

Step1:

LCM(775, 520) = 80600

GCD(775, 520) = ( 775 x 520 ) / 80600

= 775 / 520

= 775

Step2:

LCM(5, 981) = 4905

GCD(5, 981) = ( 5 x 981 ) / 4905

= 5 / 981

= 5

Step3:

LCM(1, 309) = 309

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

= 1 / 309

= 1

So, Greatest Common Divisor of 775, 520, 981, 309 is 1
