Given numbers are 261, 237, 231, 172

The list of prime factors of all numbers are

Prime factors of 261 are 3 x 3 x 29

Prime factors of 237 are 3 x 79

Prime factors of 231 are 3 x 7 x 11

Prime factors of 172 are 2 x 2 x 43

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

Given numbers are 261, 237, 231, 172

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

Apply this formula for all numbers.

Step1:

LCM(261, 237) = 20619

GCD(261, 237) = ( 261 x 237 ) / 20619

= 261 / 237

= 261

Step2:

LCM(3, 231) = 231

GCD(3, 231) = ( 3 x 231 ) / 231

= 3 / 231

= 3

Step3:

LCM(3, 172) = 516

GCD(3, 172) = ( 3 x 172 ) / 516

= 3 / 172

= 3

So, Greatest Common Divisor of 261, 237, 231, 172 is 1
