Given numbers are 297, 129, 665, 503

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

Apply this formula for all numbers.

Step1:

LCM(297, 129) = 12771

GCD(297, 129) = ( 297 x 129 ) / 12771

= 297 / 129

= 297

Step2:

LCM(3, 665) = 1995

GCD(3, 665) = ( 3 x 665 ) / 1995

= 3 / 665

= 3

Step3:

LCM(1, 503) = 503

GCD(1, 503) = ( 1 x 503 ) / 503

= 1 / 503

= 1

So, Greatest Common Divisor of 297, 129, 665, 503 is 1
