GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(302, 630) = 95130
GCD(302, 630) = ( 302 x 630 ) / 95130
= 302 / 630
= 302
Step2:
LCM(2, 788) = 788
GCD(2, 788) = ( 2 x 788 ) / 788
= 2 / 788
= 2
Step3:
LCM(2, 102) = 102
GCD(2, 102) = ( 2 x 102 ) / 102
= 2 / 102
= 2
So, Greatest Common Divisor of 302, 630, 788, 102 is 2
