Given numbers are 591, 391, 680, 187

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

Apply this formula for all numbers.

Step1:

LCM(591, 391) = 231081

GCD(591, 391) = ( 591 x 391 ) / 231081

= 591 / 391

= 591

Step2:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

Step3:

LCM(1, 187) = 187

GCD(1, 187) = ( 1 x 187 ) / 187

= 1 / 187

= 1

So, Greatest Common Divisor of 591, 391, 680, 187 is 1
