GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 989) = 613180
GCD(620, 989) = ( 620 x 989 ) / 613180
= 620 / 989
= 620
Step2:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
Step3:
LCM(1, 279) = 279
GCD(1, 279) = ( 1 x 279 ) / 279
= 1 / 279
= 1
So, Greatest Common Divisor of 620, 989, 668, 279 is 1
