Given numbers are 165, 160, 221, 572

The list of prime factors of all numbers are

Prime factors of 165 are 3 x 5 x 11

Prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 221 are 13 x 17

Prime factors of 572 are 2 x 2 x 11 x 13

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

Given numbers are 165, 160, 221, 572

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

Apply this formula for all numbers.

Step1:

LCM(165, 160) = 5280

GCD(165, 160) = ( 165 x 160 ) / 5280

= 165 / 160

= 165

Step2:

LCM(5, 221) = 1105

GCD(5, 221) = ( 5 x 221 ) / 1105

= 5 / 221

= 5

Step3:

LCM(1, 572) = 572

GCD(1, 572) = ( 1 x 572 ) / 572

= 1 / 572

= 1

So, Greatest Common Divisor of 165, 160, 221, 572 is 1
