Given numbers are 403, 488, 690, 454

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 488 are 2 x 2 x 2 x 61

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 454 are 2 x 227

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

Given numbers are 403, 488, 690, 454

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

Apply this formula for all numbers.

Step1:

LCM(403, 488) = 196664

GCD(403, 488) = ( 403 x 488 ) / 196664

= 403 / 488

= 403

Step2:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

Step3:

LCM(1, 454) = 454

GCD(1, 454) = ( 1 x 454 ) / 454

= 1 / 454

= 1

So, Greatest Common Divisor of 403, 488, 690, 454 is 1
