The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 428 are 2 x 2 x 107

Prime factors of 366 are 2 x 3 x 61

Prime factors of 253 are 11 x 23

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

Given numbers are 721, 428, 366, 253

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

Apply this formula for all numbers.

Step1:

LCM(721, 428) = 308588

GCD(721, 428) = ( 721 x 428 ) / 308588

= 721 / 428

= 721

Step2:

LCM(1, 366) = 366

GCD(1, 366) = ( 1 x 366 ) / 366

= 1 / 366

= 1

Step3:

LCM(1, 253) = 253

GCD(1, 253) = ( 1 x 253 ) / 253

= 1 / 253

= 1

So, Greatest Common Divisor of 721, 428, 366, 253 is 1
