Given numbers are 477, 641, 620, 495

The list of prime factors of all numbers are

Prime factors of 477 are 3 x 3 x 53

Prime factors of 641 are 641

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

Prime factors of 495 are 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, 641, 620, 495

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

Apply this formula for all numbers.

Step1:

LCM(477, 641) = 305757

GCD(477, 641) = ( 477 x 641 ) / 305757

= 477 / 641

= 477

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 495) = 495

GCD(1, 495) = ( 1 x 495 ) / 495

= 1 / 495

= 1

So, Greatest Common Divisor of 477, 641, 620, 495 is 1
