Given numbers are 205, 840, 67, 443

The list of prime factors of all numbers are

Prime factors of 205 are 5 x 41

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 67 are 67

Prime factors of 443 are 443

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

Given numbers are 205, 840, 67, 443

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

Apply this formula for all numbers.

Step1:

LCM(205, 840) = 34440

GCD(205, 840) = ( 205 x 840 ) / 34440

= 205 / 840

= 205

Step2:

LCM(5, 67) = 335

GCD(5, 67) = ( 5 x 67 ) / 335

= 5 / 67

= 5

Step3:

LCM(1, 443) = 443

GCD(1, 443) = ( 1 x 443 ) / 443

= 1 / 443

= 1

So, Greatest Common Divisor of 205, 840, 67, 443 is 1
