Given numbers are 871, 191, 756, 749

The list of prime factors of all numbers are

Prime factors of 871 are 13 x 67

Prime factors of 191 are 191

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 749 are 7 x 107

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

Given numbers are 871, 191, 756, 749

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

Apply this formula for all numbers.

Step1:

LCM(871, 191) = 166361

GCD(871, 191) = ( 871 x 191 ) / 166361

= 871 / 191

= 871

Step2:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

Step3:

LCM(1, 749) = 749

GCD(1, 749) = ( 1 x 749 ) / 749

= 1 / 749

= 1

So, Greatest Common Divisor of 871, 191, 756, 749 is 1
