Given numbers are 678, 448, 228, 165

The list of prime factors of all numbers are

Prime factors of 678 are 2 x 3 x 113

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

Prime factors of 228 are 2 x 2 x 3 x 19

Prime factors of 165 are 3 x 5 x 11

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

Given numbers are 678, 448, 228, 165

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

Apply this formula for all numbers.

Step1:

LCM(678, 448) = 151872

GCD(678, 448) = ( 678 x 448 ) / 151872

= 678 / 448

= 678

Step2:

LCM(2, 228) = 228

GCD(2, 228) = ( 2 x 228 ) / 228

= 2 / 228

= 2

Step3:

LCM(2, 165) = 330

GCD(2, 165) = ( 2 x 165 ) / 330

= 2 / 165

= 2

So, Greatest Common Divisor of 678, 448, 228, 165 is 1
