The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 765, 161, 457, 788
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(765, 161) = 123165
GCD(765, 161) = ( 765 x 161 ) / 123165
= 765 / 161
= 765
Step2:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
Step3:
LCM(1, 788) = 788
GCD(1, 788) = ( 1 x 788 ) / 788
= 1 / 788
= 1
So, Greatest Common Divisor of 765, 161, 457, 788 is 1
