Given numbers are 981, 428, 91, 206

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

Apply this formula for all numbers.

Step1:

LCM(981, 428) = 419868

GCD(981, 428) = ( 981 x 428 ) / 419868

= 981 / 428

= 981

Step2:

LCM(1, 91) = 91

GCD(1, 91) = ( 1 x 91 ) / 91

= 1 / 91

= 1

Step3:

LCM(1, 206) = 206

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

= 1 / 206

= 1

So, Greatest Common Divisor of 981, 428, 91, 206 is 1
