Given numbers are 820, 460, 415, 211

The list of prime factors of all numbers are

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

Prime factors of 460 are 2 x 2 x 5 x 23

Prime factors of 415 are 5 x 83

Prime factors of 211 are 211

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

Given numbers are 820, 460, 415, 211

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

Apply this formula for all numbers.

Step1:

LCM(820, 460) = 18860

GCD(820, 460) = ( 820 x 460 ) / 18860

= 820 / 460

= 820

Step2:

LCM(20, 415) = 1660

GCD(20, 415) = ( 20 x 415 ) / 1660

= 20 / 415

= 20

Step3:

LCM(5, 211) = 1055

GCD(5, 211) = ( 5 x 211 ) / 1055

= 5 / 211

= 5

So, Greatest Common Divisor of 820, 460, 415, 211 is 1
