Given numbers are 987, 257, 286, 191

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

Apply this formula for all numbers.

Step1:

LCM(987, 257) = 253659

GCD(987, 257) = ( 987 x 257 ) / 253659

= 987 / 257

= 987

Step2:

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

= 1 / 286

= 1

Step3:

LCM(1, 191) = 191

GCD(1, 191) = ( 1 x 191 ) / 191

= 1 / 191

= 1

So, Greatest Common Divisor of 987, 257, 286, 191 is 1
