Given numbers are 279, 775, 422, 686

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

Apply this formula for all numbers.

Step1:

LCM(279, 775) = 6975

GCD(279, 775) = ( 279 x 775 ) / 6975

= 279 / 775

= 279

Step2:

LCM(31, 422) = 13082

GCD(31, 422) = ( 31 x 422 ) / 13082

= 31 / 422

= 31

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 279, 775, 422, 686 is 1
