Given numbers are 987, 393, 847, 854

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

Apply this formula for all numbers.

Step1:

LCM(987, 393) = 129297

GCD(987, 393) = ( 987 x 393 ) / 129297

= 987 / 393

= 987

Step2:

LCM(3, 847) = 2541

GCD(3, 847) = ( 3 x 847 ) / 2541

= 3 / 847

= 3

Step3:

LCM(1, 854) = 854

GCD(1, 854) = ( 1 x 854 ) / 854

= 1 / 854

= 1

So, Greatest Common Divisor of 987, 393, 847, 854 is 1
