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

Apply this formula for all numbers.

Step1:

LCM(844, 980) = 206780

GCD(844, 980) = ( 844 x 980 ) / 206780

= 844 / 980

= 844

Step2:

LCM(4, 838) = 1676

GCD(4, 838) = ( 4 x 838 ) / 1676

= 4 / 838

= 4

Step3:

LCM(2, 990) = 990

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

= 2 / 990

= 2

So, Greatest Common Divisor of 844, 980, 838, 990 is 2
