Given numbers are 161, 980, 562, 360

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

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

Prime factors of 562 are 2 x 281

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

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

Given numbers are 161, 980, 562, 360

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

Apply this formula for all numbers.

Step1:

LCM(161, 980) = 22540

GCD(161, 980) = ( 161 x 980 ) / 22540

= 161 / 980

= 161

Step2:

LCM(7, 562) = 3934

GCD(7, 562) = ( 7 x 562 ) / 3934

= 7 / 562

= 7

Step3:

LCM(1, 360) = 360

GCD(1, 360) = ( 1 x 360 ) / 360

= 1 / 360

= 1

So, Greatest Common Divisor of 161, 980, 562, 360 is 1
