Given numbers are 455, 208, 626, 481

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

Prime factors of 626 are 2 x 313

Prime factors of 481 are 13 x 37

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

Given numbers are 455, 208, 626, 481

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

Apply this formula for all numbers.

Step1:

LCM(455, 208) = 7280

GCD(455, 208) = ( 455 x 208 ) / 7280

= 455 / 208

= 455

Step2:

LCM(13, 626) = 8138

GCD(13, 626) = ( 13 x 626 ) / 8138

= 13 / 626

= 13

Step3:

LCM(1, 481) = 481

GCD(1, 481) = ( 1 x 481 ) / 481

= 1 / 481

= 1

So, Greatest Common Divisor of 455, 208, 626, 481 is 1
