The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 261 are 3 x 3 x 29

Prime factors of 192 are 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 407 are 11 x 37

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

Given numbers are 721, 261, 192, 407

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

Apply this formula for all numbers.

Step1:

LCM(721, 261) = 188181

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

= 721 / 261

= 721

Step2:

LCM(1, 192) = 192

GCD(1, 192) = ( 1 x 192 ) / 192

= 1 / 192

= 1

Step3:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

So, Greatest Common Divisor of 721, 261, 192, 407 is 1
