The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

Prime factors of 849 are 3 x 283

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 365 are 5 x 73

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 161, 849, 644, 365

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(161, 849) = 136689

GCD(161, 849) = ( 161 x 849 ) / 136689

= 161 / 849

= 161

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 365) = 365

GCD(1, 365) = ( 1 x 365 ) / 365

= 1 / 365

= 1

So, Greatest Common Divisor of 161, 849, 644, 365 is 1
