Given numbers are 161, 345, 619, 452

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

Prime factors of 345 are 3 x 5 x 23

Prime factors of 619 are 619

Prime factors of 452 are 2 x 2 x 113

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

Given numbers are 161, 345, 619, 452

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

Apply this formula for all numbers.

Step1:

LCM(161, 345) = 2415

GCD(161, 345) = ( 161 x 345 ) / 2415

= 161 / 345

= 161

Step2:

LCM(23, 619) = 14237

GCD(23, 619) = ( 23 x 619 ) / 14237

= 23 / 619

= 23

Step3:

LCM(1, 452) = 452

GCD(1, 452) = ( 1 x 452 ) / 452

= 1 / 452

= 1

So, Greatest Common Divisor of 161, 345, 619, 452 is 1
