Given numbers are 920, 981, 566, 257

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

Apply this formula for all numbers.

Step1:

LCM(920, 981) = 902520

GCD(920, 981) = ( 920 x 981 ) / 902520

= 920 / 981

= 920

Step2:

LCM(1, 566) = 566

GCD(1, 566) = ( 1 x 566 ) / 566

= 1 / 566

= 1

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 920, 981, 566, 257 is 1
