Given numbers are 987, 668, 556, 587

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

Apply this formula for all numbers.

Step1:

LCM(987, 668) = 659316

GCD(987, 668) = ( 987 x 668 ) / 659316

= 987 / 668

= 987

Step2:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

Step3:

LCM(1, 587) = 587

GCD(1, 587) = ( 1 x 587 ) / 587

= 1 / 587

= 1

So, Greatest Common Divisor of 987, 668, 556, 587 is 1
