Given numbers are 987, 290, 691

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

Apply this formula for all numbers.

Step1:

LCM(987, 290) = 286230

GCD(987, 290) = ( 987 x 290 ) / 286230

= 987 / 290

= 987

Step2:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

So, Greatest Common Divisor of 987, 290, 691 is 1
