Given numbers are 427, 686, 771, 206

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

Apply this formula for all numbers.

Step1:

LCM(427, 686) = 41846

GCD(427, 686) = ( 427 x 686 ) / 41846

= 427 / 686

= 427

Step2:

LCM(7, 771) = 5397

GCD(7, 771) = ( 7 x 771 ) / 5397

= 7 / 771

= 7

Step3:

LCM(1, 206) = 206

GCD(1, 206) = ( 1 x 206 ) / 206

= 1 / 206

= 1

So, Greatest Common Divisor of 427, 686, 771, 206 is 1
