Given numbers are 390, 960, 194, 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, 960) = 12480

GCD(390, 960) = ( 390 x 960 ) / 12480

= 390 / 960

= 390

Step2:

LCM(30, 194) = 2910

GCD(30, 194) = ( 30 x 194 ) / 2910

= 30 / 194

= 30

Step3:

LCM(2, 197) = 394

GCD(2, 197) = ( 2 x 197 ) / 394

= 2 / 197

= 2

So, Greatest Common Divisor of 390, 960, 194, 197 is 1
