Given numbers are 644, 908, 997, 271

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

Apply this formula for all numbers.

Step1:

LCM(644, 908) = 146188

GCD(644, 908) = ( 644 x 908 ) / 146188

= 644 / 908

= 644

Step2:

LCM(4, 997) = 3988

GCD(4, 997) = ( 4 x 997 ) / 3988

= 4 / 997

= 4

Step3:

LCM(1, 271) = 271

GCD(1, 271) = ( 1 x 271 ) / 271

= 1 / 271

= 1

So, Greatest Common Divisor of 644, 908, 997, 271 is 1
