Given numbers are 477, 495, 620, 990

The list of prime factors of all numbers are

Prime factors of 477 are 3 x 3 x 53

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 620 are 2 x 2 x 5 x 31

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 477, 495, 620, 990

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

Apply this formula for all numbers.

Step1:

LCM(477, 495) = 26235

GCD(477, 495) = ( 477 x 495 ) / 26235

= 477 / 495

= 477

Step2:

LCM(9, 620) = 5580

GCD(9, 620) = ( 9 x 620 ) / 5580

= 9 / 620

= 9

Step3:

LCM(1, 990) = 990

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

= 1 / 990

= 1

So, Greatest Common Divisor of 477, 495, 620, 990 is 1
