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

Apply this formula for all numbers.

Step1:

LCM(979, 861) = 842919

GCD(979, 861) = ( 979 x 861 ) / 842919

= 979 / 861

= 979

Step2:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

Step3:

LCM(1, 775) = 775

GCD(1, 775) = ( 1 x 775 ) / 775

= 1 / 775

= 1

So, Greatest Common Divisor of 979, 861, 890, 775 is 1
