GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(990, 246) = 40590
GCD(990, 246) = ( 990 x 246 ) / 40590
= 990 / 246
= 990
Step2:
LCM(6, 687) = 1374
GCD(6, 687) = ( 6 x 687 ) / 1374
= 6 / 687
= 6
Step3:
LCM(3, 690) = 690
GCD(3, 690) = ( 3 x 690 ) / 690
= 3 / 690
= 3
So, Greatest Common Divisor of 990, 246, 687, 690 is 3
