Given numbers are 245, 721, 266, 874

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 721 are 7 x 103

Prime factors of 266 are 2 x 7 x 19

Prime factors of 874 are 2 x 19 x 23

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

Given numbers are 245, 721, 266, 874

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

Apply this formula for all numbers.

Step1:

LCM(245, 721) = 25235

GCD(245, 721) = ( 245 x 721 ) / 25235

= 245 / 721

= 245

Step2:

LCM(7, 266) = 266

GCD(7, 266) = ( 7 x 266 ) / 266

= 7 / 266

= 7

Step3:

LCM(7, 874) = 6118

GCD(7, 874) = ( 7 x 874 ) / 6118

= 7 / 874

= 7

So, Greatest Common Divisor of 245, 721, 266, 874 is 1
