Given numbers are 820, 228, 495, 257

The list of prime factors of all numbers are

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 228 are 2 x 2 x 3 x 19

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

Prime factors of 257 are 257

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

Given numbers are 820, 228, 495, 257

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

Apply this formula for all numbers.

Step1:

LCM(820, 228) = 46740

GCD(820, 228) = ( 820 x 228 ) / 46740

= 820 / 228

= 820

Step2:

LCM(4, 495) = 1980

GCD(4, 495) = ( 4 x 495 ) / 1980

= 4 / 495

= 4

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 820, 228, 495, 257 is 1
