Given numbers are 403, 238, 68, 880

The list of prime factors of all numbers are

Prime factors of 403 are 13 x 31

Prime factors of 238 are 2 x 7 x 17

Prime factors of 68 are 2 x 2 x 17

Prime factors of 880 are 2 x 2 x 2 x 2 x 5 x 11

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

Given numbers are 403, 238, 68, 880

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

Apply this formula for all numbers.

Step1:

LCM(403, 238) = 95914

GCD(403, 238) = ( 403 x 238 ) / 95914

= 403 / 238

= 403

Step2:

LCM(1, 68) = 68

GCD(1, 68) = ( 1 x 68 ) / 68

= 1 / 68

= 1

Step3:

LCM(1, 880) = 880

GCD(1, 880) = ( 1 x 880 ) / 880

= 1 / 880

= 1

So, Greatest Common Divisor of 403, 238, 68, 880 is 1
