Given numbers are 155, 161, 789, 375

The list of prime factors of all numbers are

Prime factors of 155 are 5 x 31

Prime factors of 161 are 7 x 23

Prime factors of 789 are 3 x 263

Prime factors of 375 are 3 x 5 x 5 x 5

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

Given numbers are 155, 161, 789, 375

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

Apply this formula for all numbers.

Step1:

LCM(155, 161) = 24955

GCD(155, 161) = ( 155 x 161 ) / 24955

= 155 / 161

= 155

Step2:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

Step3:

LCM(1, 375) = 375

GCD(1, 375) = ( 1 x 375 ) / 375

= 1 / 375

= 1

So, Greatest Common Divisor of 155, 161, 789, 375 is 1
