Given numbers are 663, 997, 787, 311

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

Apply this formula for all numbers.

Step1:

LCM(663, 997) = 661011

GCD(663, 997) = ( 663 x 997 ) / 661011

= 663 / 997

= 663

Step2:

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

= 1 / 787

= 1

Step3:

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

= 1 / 311

= 1

So, Greatest Common Divisor of 663, 997, 787, 311 is 1
