Given numbers are 505, 486, 394, 178

The list of prime factors of all numbers are

Prime factors of 505 are 5 x 101

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

Prime factors of 394 are 2 x 197

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 505, 486, 394, 178

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

Apply this formula for all numbers.

Step1:

LCM(505, 486) = 245430

GCD(505, 486) = ( 505 x 486 ) / 245430

= 505 / 486

= 505

Step2:

LCM(1, 394) = 394

GCD(1, 394) = ( 1 x 394 ) / 394

= 1 / 394

= 1

Step3:

LCM(1, 178) = 178

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

= 1 / 178

= 1

So, Greatest Common Divisor of 505, 486, 394, 178 is 1
