Given numbers are 806, 194, 931, 991

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

Apply this formula for all numbers.

Step1:

LCM(806, 194) = 78182

GCD(806, 194) = ( 806 x 194 ) / 78182

= 806 / 194

= 806

Step2:

LCM(2, 931) = 1862

GCD(2, 931) = ( 2 x 931 ) / 1862

= 2 / 931

= 2

Step3:

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

= 1 / 991

= 1

So, Greatest Common Divisor of 806, 194, 931, 991 is 1
