Given numbers are 820, 789, 178, 908

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

Apply this formula for all numbers.

Step1:

LCM(820, 789) = 646980

GCD(820, 789) = ( 820 x 789 ) / 646980

= 820 / 789

= 820

Step2:

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

= 1 / 178

= 1

Step3:

LCM(1, 908) = 908

GCD(1, 908) = ( 1 x 908 ) / 908

= 1 / 908

= 1

So, Greatest Common Divisor of 820, 789, 178, 908 is 1
