GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 173) = 84943
GCD(491, 173) = ( 491 x 173 ) / 84943
= 491 / 173
= 491
Step2:
LCM(1, 799) = 799
GCD(1, 799) = ( 1 x 799 ) / 799
= 1 / 799
= 1
Step3:
LCM(1, 421) = 421
GCD(1, 421) = ( 1 x 421 ) / 421
= 1 / 421
= 1
So, Greatest Common Divisor of 491, 173, 799, 421 is 1
