Given numbers are 403, 676, 621, 998

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

Apply this formula for all numbers.

Step1:

LCM(403, 676) = 20956

GCD(403, 676) = ( 403 x 676 ) / 20956

= 403 / 676

= 403

Step2:

LCM(13, 621) = 8073

GCD(13, 621) = ( 13 x 621 ) / 8073

= 13 / 621

= 13

Step3:

LCM(1, 998) = 998

GCD(1, 998) = ( 1 x 998 ) / 998

= 1 / 998

= 1

So, Greatest Common Divisor of 403, 676, 621, 998 is 1
