Given numbers are 721, 871, 126, 717

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 871 are 13 x 67

Prime factors of 126 are 2 x 3 x 3 x 7

Prime factors of 717 are 3 x 239

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

Given numbers are 721, 871, 126, 717

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

Apply this formula for all numbers.

Step1:

LCM(721, 871) = 627991

GCD(721, 871) = ( 721 x 871 ) / 627991

= 721 / 871

= 721

Step2:

LCM(1, 126) = 126

GCD(1, 126) = ( 1 x 126 ) / 126

= 1 / 126

= 1

Step3:

LCM(1, 717) = 717

GCD(1, 717) = ( 1 x 717 ) / 717

= 1 / 717

= 1

So, Greatest Common Divisor of 721, 871, 126, 717 is 1
