Given numbers are 210, 805, 392, 804

The list of prime factors of all numbers are

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 805 are 5 x 7 x 23

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

Prime factors of 804 are 2 x 2 x 3 x 67

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

Given numbers are 210, 805, 392, 804

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

Apply this formula for all numbers.

Step1:

LCM(210, 805) = 4830

GCD(210, 805) = ( 210 x 805 ) / 4830

= 210 / 805

= 210

Step2:

LCM(35, 392) = 1960

GCD(35, 392) = ( 35 x 392 ) / 1960

= 35 / 392

= 35

Step3:

LCM(7, 804) = 5628

GCD(7, 804) = ( 7 x 804 ) / 5628

= 7 / 804

= 7

So, Greatest Common Divisor of 210, 805, 392, 804 is 1
