Given numbers are 844, 865, 820, 251

The list of prime factors of all numbers are

Prime factors of 844 are 2 x 2 x 211

Prime factors of 865 are 5 x 173

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

Prime factors of 251 are 251

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

Given numbers are 844, 865, 820, 251

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

Apply this formula for all numbers.

Step1:

LCM(844, 865) = 730060

GCD(844, 865) = ( 844 x 865 ) / 730060

= 844 / 865

= 844

Step2:

LCM(1, 820) = 820

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

= 1 / 820

= 1

Step3:

LCM(1, 251) = 251

GCD(1, 251) = ( 1 x 251 ) / 251

= 1 / 251

= 1

So, Greatest Common Divisor of 844, 865, 820, 251 is 1
