The list of prime factors of all numbers are
Prime factors of 765 are 3 x 3 x 5 x 17
Prime factors of 355 are 5 x 71
Prime factors of 644 are 2 x 2 x 7 x 23
Prime factors of 618 are 2 x 3 x 103
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 765, 355, 644, 618
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(765, 355) = 54315
GCD(765, 355) = ( 765 x 355 ) / 54315
= 765 / 355
= 765
Step2:
LCM(5, 644) = 3220
GCD(5, 644) = ( 5 x 644 ) / 3220
= 5 / 644
= 5
Step3:
LCM(1, 618) = 618
GCD(1, 618) = ( 1 x 618 ) / 618
= 1 / 618
= 1
So, Greatest Common Divisor of 765, 355, 644, 618 is 1
