Given numbers are 511, 943, 789, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(511, 943) = 481873
GCD(511, 943) = ( 511 x 943 ) / 481873
= 511 / 943
= 511
Step2:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 511, 943, 789, 644 is 1
