Given numbers are 681, 991, 980, 206

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

Apply this formula for all numbers.

Step1:

LCM(681, 991) = 674871

GCD(681, 991) = ( 681 x 991 ) / 674871

= 681 / 991

= 681

Step2:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

Step3:

LCM(1, 206) = 206

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

= 1 / 206

= 1

So, Greatest Common Divisor of 681, 991, 980, 206 is 1
