Given numbers are 188, 680, 205, 789

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

Apply this formula for all numbers.

Step1:

LCM(188, 680) = 31960

GCD(188, 680) = ( 188 x 680 ) / 31960

= 188 / 680

= 188

Step2:

LCM(4, 205) = 820

GCD(4, 205) = ( 4 x 205 ) / 820

= 4 / 205

= 4

Step3:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

So, Greatest Common Divisor of 188, 680, 205, 789 is 1
