Given numbers are 477, 278, 768, 178

The list of prime factors of all numbers are

Prime factors of 477 are 3 x 3 x 53

Prime factors of 278 are 2 x 139

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 178 are 2 x 89

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

Given numbers are 477, 278, 768, 178

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

Apply this formula for all numbers.

Step1:

LCM(477, 278) = 132606

GCD(477, 278) = ( 477 x 278 ) / 132606

= 477 / 278

= 477

Step2:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

Step3:

LCM(1, 178) = 178

GCD(1, 178) = ( 1 x 178 ) / 178

= 1 / 178

= 1

So, Greatest Common Divisor of 477, 278, 768, 178 is 1
