Given numbers are 253, 454, 791, 208

The list of prime factors of all numbers are

Prime factors of 253 are 11 x 23

Prime factors of 454 are 2 x 227

Prime factors of 791 are 7 x 113

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

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

Given numbers are 253, 454, 791, 208

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

Apply this formula for all numbers.

Step1:

LCM(253, 454) = 114862

GCD(253, 454) = ( 253 x 454 ) / 114862

= 253 / 454

= 253

Step2:

LCM(1, 791) = 791

GCD(1, 791) = ( 1 x 791 ) / 791

= 1 / 791

= 1

Step3:

LCM(1, 208) = 208

GCD(1, 208) = ( 1 x 208 ) / 208

= 1 / 208

= 1

So, Greatest Common Divisor of 253, 454, 791, 208 is 1
