Given numbers are 389, 570, 400, 220

The list of prime factors of all numbers are

Prime factors of 389 are 389

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

Prime factors of 220 are 2 x 2 x 5 x 11

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

Given numbers are 389, 570, 400, 220

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

Apply this formula for all numbers.

Step1:

LCM(389, 570) = 221730

GCD(389, 570) = ( 389 x 570 ) / 221730

= 389 / 570

= 389

Step2:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 389, 570, 400, 220 is 1
