Given numbers are 989, 399, 831, 328

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

Apply this formula for all numbers.

Step1:

LCM(989, 399) = 394611

GCD(989, 399) = ( 989 x 399 ) / 394611

= 989 / 399

= 989

Step2:

LCM(1, 831) = 831

GCD(1, 831) = ( 1 x 831 ) / 831

= 1 / 831

= 1

Step3:

LCM(1, 328) = 328

GCD(1, 328) = ( 1 x 328 ) / 328

= 1 / 328

= 1

So, Greatest Common Divisor of 989, 399, 831, 328 is 1
