The list of prime factors of all numbers are

Prime factors of 657 are 3 x 3 x 73

Prime factors of 410 are 2 x 5 x 41

Prime factors of 477 are 3 x 3 x 53

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

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

Given numbers are 657, 410, 477, 990

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

Apply this formula for all numbers.

Step1:

LCM(657, 410) = 269370

GCD(657, 410) = ( 657 x 410 ) / 269370

= 657 / 410

= 657

Step2:

LCM(1, 477) = 477

GCD(1, 477) = ( 1 x 477 ) / 477

= 1 / 477

= 1

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 657, 410, 477, 990 is 1
