Given numbers are 989, 781, 502, 399

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

Apply this formula for all numbers.

Step1:

LCM(989, 781) = 772409

GCD(989, 781) = ( 989 x 781 ) / 772409

= 989 / 781

= 989

Step2:

LCM(1, 502) = 502

GCD(1, 502) = ( 1 x 502 ) / 502

= 1 / 502

= 1

Step3:

LCM(1, 399) = 399

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

= 1 / 399

= 1

So, Greatest Common Divisor of 989, 781, 502, 399 is 1
