Given numbers are 475, 378, 278, 636

The list of prime factors of all numbers are

Prime factors of 475 are 5 x 5 x 19

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 278 are 2 x 139

Prime factors of 636 are 2 x 2 x 3 x 53

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

Given numbers are 475, 378, 278, 636

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

Apply this formula for all numbers.

Step1:

LCM(475, 378) = 179550

GCD(475, 378) = ( 475 x 378 ) / 179550

= 475 / 378

= 475

Step2:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

Step3:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

So, Greatest Common Divisor of 475, 378, 278, 636 is 1
