Given numbers are 390, 249, 712, 197

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

Apply this formula for all numbers.

Step1:

LCM(390, 249) = 32370

GCD(390, 249) = ( 390 x 249 ) / 32370

= 390 / 249

= 390

Step2:

LCM(3, 712) = 2136

GCD(3, 712) = ( 3 x 712 ) / 2136

= 3 / 712

= 3

Step3:

LCM(1, 197) = 197

GCD(1, 197) = ( 1 x 197 ) / 197

= 1 / 197

= 1

So, Greatest Common Divisor of 390, 249, 712, 197 is 1
