Given numbers are 821, 920, 258, 818

The list of prime factors of all numbers are

Prime factors of 821 are 821

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 258 are 2 x 3 x 43

Prime factors of 818 are 2 x 409

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

Given numbers are 821, 920, 258, 818

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

Apply this formula for all numbers.

Step1:

LCM(821, 920) = 755320

GCD(821, 920) = ( 821 x 920 ) / 755320

= 821 / 920

= 821

Step2:

LCM(1, 258) = 258

GCD(1, 258) = ( 1 x 258 ) / 258

= 1 / 258

= 1

Step3:

LCM(1, 818) = 818

GCD(1, 818) = ( 1 x 818 ) / 818

= 1 / 818

= 1

So, Greatest Common Divisor of 821, 920, 258, 818 is 1
