Given numbers are 771, 820, 803, 813

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

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

Prime factors of 803 are 11 x 73

Prime factors of 813 are 3 x 271

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

Given numbers are 771, 820, 803, 813

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

Apply this formula for all numbers.

Step1:

LCM(771, 820) = 632220

GCD(771, 820) = ( 771 x 820 ) / 632220

= 771 / 820

= 771

Step2:

LCM(1, 803) = 803

GCD(1, 803) = ( 1 x 803 ) / 803

= 1 / 803

= 1

Step3:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 771, 820, 803, 813 is 1
