Given numbers are 221, 137, 144, 539

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

Apply this formula for all numbers.

Step1:

LCM(221, 137) = 30277

GCD(221, 137) = ( 221 x 137 ) / 30277

= 221 / 137

= 221

Step2:

LCM(1, 144) = 144

GCD(1, 144) = ( 1 x 144 ) / 144

= 1 / 144

= 1

Step3:

LCM(1, 539) = 539

GCD(1, 539) = ( 1 x 539 ) / 539

= 1 / 539

= 1

So, Greatest Common Divisor of 221, 137, 144, 539 is 1
