GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 743) = 482207
GCD(649, 743) = ( 649 x 743 ) / 482207
= 649 / 743
= 649
Step2:
LCM(1, 979) = 979
GCD(1, 979) = ( 1 x 979 ) / 979
= 1 / 979
= 1
Step3:
LCM(1, 605) = 605
GCD(1, 605) = ( 1 x 605 ) / 605
= 1 / 605
= 1
So, Greatest Common Divisor of 649, 743, 979, 605 is 1
