Given numbers are 203, 178, 448, 816

The list of prime factors of all numbers are

Prime factors of 203 are 7 x 29

Prime factors of 178 are 2 x 89

Prime factors of 448 are 2 x 2 x 2 x 2 x 2 x 2 x 7

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

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

Given numbers are 203, 178, 448, 816

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

Apply this formula for all numbers.

Step1:

LCM(203, 178) = 36134

GCD(203, 178) = ( 203 x 178 ) / 36134

= 203 / 178

= 203

Step2:

LCM(1, 448) = 448

GCD(1, 448) = ( 1 x 448 ) / 448

= 1 / 448

= 1

Step3:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

So, Greatest Common Divisor of 203, 178, 448, 816 is 1
