Given numbers are 620, 398, 958, 963

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

Apply this formula for all numbers.

Step1:

LCM(620, 398) = 123380

GCD(620, 398) = ( 620 x 398 ) / 123380

= 620 / 398

= 620

Step2:

LCM(2, 958) = 958

GCD(2, 958) = ( 2 x 958 ) / 958

= 2 / 958

= 2

Step3:

LCM(2, 963) = 1926

GCD(2, 963) = ( 2 x 963 ) / 1926

= 2 / 963

= 2

So, Greatest Common Divisor of 620, 398, 958, 963 is 1
