Given numbers are 390, 204, 85, 697

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

Apply this formula for all numbers.

Step1:

LCM(390, 204) = 13260

GCD(390, 204) = ( 390 x 204 ) / 13260

= 390 / 204

= 390

Step2:

LCM(6, 85) = 510

GCD(6, 85) = ( 6 x 85 ) / 510

= 6 / 85

= 6

Step3:

LCM(1, 697) = 697

GCD(1, 697) = ( 1 x 697 ) / 697

= 1 / 697

= 1

So, Greatest Common Divisor of 390, 204, 85, 697 is 1
