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

Apply this formula for all numbers.

Step1:

LCM(981, 186) = 60822

GCD(981, 186) = ( 981 x 186 ) / 60822

= 981 / 186

= 981

Step2:

LCM(3, 69) = 69

GCD(3, 69) = ( 3 x 69 ) / 69

= 3 / 69

= 3

Step3:

LCM(3, 306) = 306

GCD(3, 306) = ( 3 x 306 ) / 306

= 3 / 306

= 3

So, Greatest Common Divisor of 981, 186, 69, 306 is 3
