GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(123, 798) = 32718
GCD(123, 798) = ( 123 x 798 ) / 32718
= 123 / 798
= 123
Step2:
LCM(3, 988) = 2964
GCD(3, 988) = ( 3 x 988 ) / 2964
= 3 / 988
= 3
Step3:
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
= 1 / 423
= 1
So, Greatest Common Divisor of 123, 798, 988, 423 is 1
