Given numbers are 816, 168, 997, 399

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

Apply this formula for all numbers.

Step1:

LCM(816, 168) = 5712

GCD(816, 168) = ( 816 x 168 ) / 5712

= 816 / 168

= 816

Step2:

LCM(24, 997) = 23928

GCD(24, 997) = ( 24 x 997 ) / 23928

= 24 / 997

= 24

Step3:

LCM(1, 399) = 399

GCD(1, 399) = ( 1 x 399 ) / 399

= 1 / 399

= 1

So, Greatest Common Divisor of 816, 168, 997, 399 is 1
