Given numbers are 209, 771, 785, 274

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

Apply this formula for all numbers.

Step1:

LCM(209, 771) = 161139

GCD(209, 771) = ( 209 x 771 ) / 161139

= 209 / 771

= 209

Step2:

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

= 1 / 785

= 1

Step3:

LCM(1, 274) = 274

GCD(1, 274) = ( 1 x 274 ) / 274

= 1 / 274

= 1

So, Greatest Common Divisor of 209, 771, 785, 274 is 1
