Given numbers are 211, 175, 665, 981

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

Apply this formula for all numbers.

Step1:

LCM(211, 175) = 36925

GCD(211, 175) = ( 211 x 175 ) / 36925

= 211 / 175

= 211

Step2:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

Step3:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

So, Greatest Common Divisor of 211, 175, 665, 981 is 1
