Given numbers are 990, 787, 27, 684

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

Apply this formula for all numbers.

Step1:

LCM(990, 787) = 779130

GCD(990, 787) = ( 990 x 787 ) / 779130

= 990 / 787

= 990

Step2:

LCM(1, 27) = 27

GCD(1, 27) = ( 1 x 27 ) / 27

= 1 / 27

= 1

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 990, 787, 27, 684 is 1
