Given numbers are 161, 489, 235, 550

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

Prime factors of 489 are 3 x 163

Prime factors of 235 are 5 x 47

Prime factors of 550 are 2 x 5 x 5 x 11

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

Given numbers are 161, 489, 235, 550

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

Apply this formula for all numbers.

Step1:

LCM(161, 489) = 78729

GCD(161, 489) = ( 161 x 489 ) / 78729

= 161 / 489

= 161

Step2:

LCM(1, 235) = 235

GCD(1, 235) = ( 1 x 235 ) / 235

= 1 / 235

= 1

Step3:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

So, Greatest Common Divisor of 161, 489, 235, 550 is 1
