Given numbers are 620, 568, 720, 988

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

Apply this formula for all numbers.

Step1:

LCM(620, 568) = 88040

GCD(620, 568) = ( 620 x 568 ) / 88040

= 620 / 568

= 620

Step2:

LCM(4, 720) = 720

GCD(4, 720) = ( 4 x 720 ) / 720

= 4 / 720

= 4

Step3:

LCM(4, 988) = 988

GCD(4, 988) = ( 4 x 988 ) / 988

= 4 / 988

= 4

So, Greatest Common Divisor of 620, 568, 720, 988 is 4
