Given numbers are 765, 643, 849, 171
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(765, 643) = 491895
GCD(765, 643) = ( 765 x 643 ) / 491895
= 765 / 643
= 765
Step2:
LCM(1, 849) = 849
GCD(1, 849) = ( 1 x 849 ) / 849
= 1 / 849
= 1
Step3:
LCM(1, 171) = 171
GCD(1, 171) = ( 1 x 171 ) / 171
= 1 / 171
= 1
So, Greatest Common Divisor of 765, 643, 849, 171 is 1
