Given numbers are 390, 568, 797, 665

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

Apply this formula for all numbers.

Step1:

LCM(390, 568) = 110760

GCD(390, 568) = ( 390 x 568 ) / 110760

= 390 / 568

= 390

Step2:

LCM(2, 797) = 1594

GCD(2, 797) = ( 2 x 797 ) / 1594

= 2 / 797

= 2

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 390, 568, 797, 665 is 1
