Given numbers are 211, 745, 40, 287

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

Apply this formula for all numbers.

Step1:

LCM(211, 745) = 157195

GCD(211, 745) = ( 211 x 745 ) / 157195

= 211 / 745

= 211

Step2:

LCM(1, 40) = 40

GCD(1, 40) = ( 1 x 40 ) / 40

= 1 / 40

= 1

Step3:

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

= 1 / 287

= 1

So, Greatest Common Divisor of 211, 745, 40, 287 is 1
