Given numbers are 997, 129, 439, 864

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

Apply this formula for all numbers.

Step1:

LCM(997, 129) = 128613

GCD(997, 129) = ( 997 x 129 ) / 128613

= 997 / 129

= 997

Step2:

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

= 1 / 439

= 1

Step3:

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

= 1 / 864

= 1

So, Greatest Common Divisor of 997, 129, 439, 864 is 1
