Given numbers are 455, 318, 691, 722

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 318 are 2 x 3 x 53

Prime factors of 691 are 691

Prime factors of 722 are 2 x 19 x 19

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

Given numbers are 455, 318, 691, 722

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

Apply this formula for all numbers.

Step1:

LCM(455, 318) = 144690

GCD(455, 318) = ( 455 x 318 ) / 144690

= 455 / 318

= 455

Step2:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

Step3:

LCM(1, 722) = 722

GCD(1, 722) = ( 1 x 722 ) / 722

= 1 / 722

= 1

So, Greatest Common Divisor of 455, 318, 691, 722 is 1
