Given numbers are 510, 780, 938, 990

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

Apply this formula for all numbers.

Step1:

LCM(510, 780) = 13260

GCD(510, 780) = ( 510 x 780 ) / 13260

= 510 / 780

= 510

Step2:

LCM(30, 938) = 14070

GCD(30, 938) = ( 30 x 938 ) / 14070

= 30 / 938

= 30

Step3:

LCM(2, 990) = 990

GCD(2, 990) = ( 2 x 990 ) / 990

= 2 / 990

= 2

So, Greatest Common Divisor of 510, 780, 938, 990 is 2
