Given numbers are 565, 154, 221, 531

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

Apply this formula for all numbers.

Step1:

LCM(565, 154) = 87010

GCD(565, 154) = ( 565 x 154 ) / 87010

= 565 / 154

= 565

Step2:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

Step3:

LCM(1, 531) = 531

GCD(1, 531) = ( 1 x 531 ) / 531

= 1 / 531

= 1

So, Greatest Common Divisor of 565, 154, 221, 531 is 1
