Given numbers are 805, 697, 197, 778

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

Apply this formula for all numbers.

Step1:

LCM(805, 697) = 561085

GCD(805, 697) = ( 805 x 697 ) / 561085

= 805 / 697

= 805

Step2:

LCM(1, 197) = 197

GCD(1, 197) = ( 1 x 197 ) / 197

= 1 / 197

= 1

Step3:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

So, Greatest Common Divisor of 805, 697, 197, 778 is 1
