Given numbers are 399, 431, 991, 837

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

Apply this formula for all numbers.

Step1:

LCM(399, 431) = 171969

GCD(399, 431) = ( 399 x 431 ) / 171969

= 399 / 431

= 399

Step2:

LCM(1, 991) = 991

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

= 1 / 991

= 1

Step3:

LCM(1, 837) = 837

GCD(1, 837) = ( 1 x 837 ) / 837

= 1 / 837

= 1

So, Greatest Common Divisor of 399, 431, 991, 837 is 1
