Given numbers are 280, 561, 169, 167

The list of prime factors of all numbers are

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 561 are 3 x 11 x 17

Prime factors of 169 are 13 x 13

Prime factors of 167 are 167

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

Given numbers are 280, 561, 169, 167

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

Apply this formula for all numbers.

Step1:

LCM(280, 561) = 157080

GCD(280, 561) = ( 280 x 561 ) / 157080

= 280 / 561

= 280

Step2:

LCM(1, 169) = 169

GCD(1, 169) = ( 1 x 169 ) / 169

= 1 / 169

= 1

Step3:

LCM(1, 167) = 167

GCD(1, 167) = ( 1 x 167 ) / 167

= 1 / 167

= 1

So, Greatest Common Divisor of 280, 561, 169, 167 is 1
