GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(116, 638) = 1276
GCD(116, 638) = ( 116 x 638 ) / 1276
= 116 / 638
= 116
Step2:
LCM(58, 890) = 25810
GCD(58, 890) = ( 58 x 890 ) / 25810
= 58 / 890
= 58
Step3:
LCM(2, 490) = 490
GCD(2, 490) = ( 2 x 490 ) / 490
= 2 / 490
= 2
So, Greatest Common Divisor of 116, 638, 890, 490 is 2
