Given numbers are 455, 361, 521, 828

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 361 are 19 x 19

Prime factors of 521 are 521

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

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

Given numbers are 455, 361, 521, 828

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

Apply this formula for all numbers.

Step1:

LCM(455, 361) = 164255

GCD(455, 361) = ( 455 x 361 ) / 164255

= 455 / 361

= 455

Step2:

LCM(1, 521) = 521

GCD(1, 521) = ( 1 x 521 ) / 521

= 1 / 521

= 1

Step3:

LCM(1, 828) = 828

GCD(1, 828) = ( 1 x 828 ) / 828

= 1 / 828

= 1

So, Greatest Common Divisor of 455, 361, 521, 828 is 1
