Given numbers are 811, 470, 620, 189

The list of prime factors of all numbers are

Prime factors of 811 are 811

Prime factors of 470 are 2 x 5 x 47

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 189 are 3 x 3 x 3 x 7

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

Given numbers are 811, 470, 620, 189

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

Apply this formula for all numbers.

Step1:

LCM(811, 470) = 381170

GCD(811, 470) = ( 811 x 470 ) / 381170

= 811 / 470

= 811

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 811, 470, 620, 189 is 1
