Given numbers are 721, 455, 889, 361

The list of prime factors of all numbers are

Prime factors of 721 are 7 x 103

Prime factors of 455 are 5 x 7 x 13

Prime factors of 889 are 7 x 127

Prime factors of 361 are 19 x 19

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

Given numbers are 721, 455, 889, 361

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

Apply this formula for all numbers.

Step1:

LCM(721, 455) = 46865

GCD(721, 455) = ( 721 x 455 ) / 46865

= 721 / 455

= 721

Step2:

LCM(7, 889) = 889

GCD(7, 889) = ( 7 x 889 ) / 889

= 7 / 889

= 7

Step3:

LCM(7, 361) = 2527

GCD(7, 361) = ( 7 x 361 ) / 2527

= 7 / 361

= 7

So, Greatest Common Divisor of 721, 455, 889, 361 is 1
