Given numbers are 161, 255, 350, 980

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

Prime factors of 255 are 3 x 5 x 17

Prime factors of 350 are 2 x 5 x 5 x 7

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

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

Given numbers are 161, 255, 350, 980

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

Apply this formula for all numbers.

Step1:

LCM(161, 255) = 41055

GCD(161, 255) = ( 161 x 255 ) / 41055

= 161 / 255

= 161

Step2:

LCM(1, 350) = 350

GCD(1, 350) = ( 1 x 350 ) / 350

= 1 / 350

= 1

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 161, 255, 350, 980 is 1
