Given numbers are 391, 844, 399, 983

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

Apply this formula for all numbers.

Step1:

LCM(391, 844) = 330004

GCD(391, 844) = ( 391 x 844 ) / 330004

= 391 / 844

= 391

Step2:

LCM(1, 399) = 399

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

= 1 / 399

= 1

Step3:

LCM(1, 983) = 983

GCD(1, 983) = ( 1 x 983 ) / 983

= 1 / 983

= 1

So, Greatest Common Divisor of 391, 844, 399, 983 is 1
