Given numbers are 391, 816, 891, 493

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

Apply this formula for all numbers.

Step1:

LCM(391, 816) = 18768

GCD(391, 816) = ( 391 x 816 ) / 18768

= 391 / 816

= 391

Step2:

LCM(17, 891) = 15147

GCD(17, 891) = ( 17 x 891 ) / 15147

= 17 / 891

= 17

Step3:

LCM(1, 493) = 493

GCD(1, 493) = ( 1 x 493 ) / 493

= 1 / 493

= 1

So, Greatest Common Divisor of 391, 816, 891, 493 is 1
