Given numbers are 403, 812, 991, 819

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

Apply this formula for all numbers.

Step1:

LCM(403, 812) = 327236

GCD(403, 812) = ( 403 x 812 ) / 327236

= 403 / 812

= 403

Step2:

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

= 1 / 991

= 1

Step3:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

So, Greatest Common Divisor of 403, 812, 991, 819 is 1
