The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

Prime factors of 133 are 7 x 19

Prime factors of 202 are 2 x 101

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

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

Given numbers are 771, 133, 202, 820

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

Apply this formula for all numbers.

Step1:

LCM(771, 133) = 102543

GCD(771, 133) = ( 771 x 133 ) / 102543

= 771 / 133

= 771

Step2:

LCM(1, 202) = 202

GCD(1, 202) = ( 1 x 202 ) / 202

= 1 / 202

= 1

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 771, 133, 202, 820 is 1
