Given numbers are 208, 640, 745, 727

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

Apply this formula for all numbers.

Step1:

LCM(208, 640) = 8320

GCD(208, 640) = ( 208 x 640 ) / 8320

= 208 / 640

= 208

Step2:

LCM(16, 745) = 11920

GCD(16, 745) = ( 16 x 745 ) / 11920

= 16 / 745

= 16

Step3:

LCM(1, 727) = 727

GCD(1, 727) = ( 1 x 727 ) / 727

= 1 / 727

= 1

So, Greatest Common Divisor of 208, 640, 745, 727 is 1
