Given numbers are 132, 245, 809, 257

The list of prime factors of all numbers are

Prime factors of 132 are 2 x 2 x 3 x 11

Prime factors of 245 are 5 x 7 x 7

Prime factors of 809 are 809

Prime factors of 257 are 257

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

Given numbers are 132, 245, 809, 257

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

Apply this formula for all numbers.

Step1:

LCM(132, 245) = 32340

GCD(132, 245) = ( 132 x 245 ) / 32340

= 132 / 245

= 132

Step2:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 132, 245, 809, 257 is 1
