Given numbers are 202, 855, 231, 280

The list of prime factors of all numbers are

Prime factors of 202 are 2 x 101

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 231 are 3 x 7 x 11

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

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

Given numbers are 202, 855, 231, 280

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

Apply this formula for all numbers.

Step1:

LCM(202, 855) = 172710

GCD(202, 855) = ( 202 x 855 ) / 172710

= 202 / 855

= 202

Step2:

LCM(1, 231) = 231

GCD(1, 231) = ( 1 x 231 ) / 231

= 1 / 231

= 1

Step3:

LCM(1, 280) = 280

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

= 1 / 280

= 1

So, Greatest Common Divisor of 202, 855, 231, 280 is 1
