Given numbers are 194, 188, 806, 780

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

Apply this formula for all numbers.

Step1:

LCM(194, 188) = 18236

GCD(194, 188) = ( 194 x 188 ) / 18236

= 194 / 188

= 194

Step2:

LCM(2, 806) = 806

GCD(2, 806) = ( 2 x 806 ) / 806

= 2 / 806

= 2

Step3:

LCM(2, 780) = 780

GCD(2, 780) = ( 2 x 780 ) / 780

= 2 / 780

= 2

So, Greatest Common Divisor of 194, 188, 806, 780 is 2
