Given numbers are 111, 711, 389, 249

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

Apply this formula for all numbers.

Step1:

LCM(111, 711) = 26307

GCD(111, 711) = ( 111 x 711 ) / 26307

= 111 / 711

= 111

Step2:

LCM(3, 389) = 1167

GCD(3, 389) = ( 3 x 389 ) / 1167

= 3 / 389

= 3

Step3:

LCM(1, 249) = 249

GCD(1, 249) = ( 1 x 249 ) / 249

= 1 / 249

= 1

So, Greatest Common Divisor of 111, 711, 389, 249 is 1
