Given numbers are 197, 820, 503

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

Apply this formula for all numbers.

Step1:

LCM(197, 820) = 161540

GCD(197, 820) = ( 197 x 820 ) / 161540

= 197 / 820

= 197

Step2:

LCM(1, 503) = 503

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

= 1 / 503

= 1

So, Greatest Common Divisor of 197, 820, 503 is 1
