Given numbers are 261, 721, 156, 271

The list of prime factors of all numbers are

Prime factors of 261 are 3 x 3 x 29

Prime factors of 721 are 7 x 103

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 271 are 271

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

Given numbers are 261, 721, 156, 271

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

Apply this formula for all numbers.

Step1:

LCM(261, 721) = 188181

GCD(261, 721) = ( 261 x 721 ) / 188181

= 261 / 721

= 261

Step2:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

Step3:

LCM(1, 271) = 271

GCD(1, 271) = ( 1 x 271 ) / 271

= 1 / 271

= 1

So, Greatest Common Divisor of 261, 721, 156, 271 is 1
