Given numbers are 121, 445, 280, 187

The list of prime factors of all numbers are

Prime factors of 121 are 11 x 11

Prime factors of 445 are 5 x 89

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

Prime factors of 187 are 11 x 17

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

Given numbers are 121, 445, 280, 187

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

Apply this formula for all numbers.

Step1:

LCM(121, 445) = 53845

GCD(121, 445) = ( 121 x 445 ) / 53845

= 121 / 445

= 121

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

Step3:

LCM(1, 187) = 187

GCD(1, 187) = ( 1 x 187 ) / 187

= 1 / 187

= 1

So, Greatest Common Divisor of 121, 445, 280, 187 is 1
