Given numbers are 207, 711, 124, 257

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

Apply this formula for all numbers.

Step1:

LCM(207, 711) = 16353

GCD(207, 711) = ( 207 x 711 ) / 16353

= 207 / 711

= 207

Step2:

LCM(9, 124) = 1116

GCD(9, 124) = ( 9 x 124 ) / 1116

= 9 / 124

= 9

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 207, 711, 124, 257 is 1
