Given numbers are 693, 390, 268, 858

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

Apply this formula for all numbers.

Step1:

LCM(693, 390) = 90090

GCD(693, 390) = ( 693 x 390 ) / 90090

= 693 / 390

= 693

Step2:

LCM(3, 268) = 804

GCD(3, 268) = ( 3 x 268 ) / 804

= 3 / 268

= 3

Step3:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

So, Greatest Common Divisor of 693, 390, 268, 858 is 1
