Given numbers are 987, 403, 391, 383

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

Apply this formula for all numbers.

Step1:

LCM(987, 403) = 397761

GCD(987, 403) = ( 987 x 403 ) / 397761

= 987 / 403

= 987

Step2:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

Step3:

LCM(1, 383) = 383

GCD(1, 383) = ( 1 x 383 ) / 383

= 1 / 383

= 1

So, Greatest Common Divisor of 987, 403, 391, 383 is 1
