Given numbers are 306, 687, 383, 981

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

Apply this formula for all numbers.

Step1:

LCM(306, 687) = 70074

GCD(306, 687) = ( 306 x 687 ) / 70074

= 306 / 687

= 306

Step2:

LCM(3, 383) = 1149

GCD(3, 383) = ( 3 x 383 ) / 1149

= 3 / 383

= 3

Step3:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

So, Greatest Common Divisor of 306, 687, 383, 981 is 1
