Given numbers are 566, 752, 21, 257

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

Apply this formula for all numbers.

Step1:

LCM(566, 752) = 212816

GCD(566, 752) = ( 566 x 752 ) / 212816

= 566 / 752

= 566

Step2:

LCM(2, 21) = 42

GCD(2, 21) = ( 2 x 21 ) / 42

= 2 / 21

= 2

Step3:

LCM(1, 257) = 257

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

= 1 / 257

= 1

So, Greatest Common Divisor of 566, 752, 21, 257 is 1
