Given numbers are 165, 272, 215, 853

The list of prime factors of all numbers are

Prime factors of 165 are 3 x 5 x 11

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

Prime factors of 215 are 5 x 43

Prime factors of 853 are 853

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

Given numbers are 165, 272, 215, 853

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

Apply this formula for all numbers.

Step1:

LCM(165, 272) = 44880

GCD(165, 272) = ( 165 x 272 ) / 44880

= 165 / 272

= 165

Step2:

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

= 1 / 215

= 1

Step3:

LCM(1, 853) = 853

GCD(1, 853) = ( 1 x 853 ) / 853

= 1 / 853

= 1

So, Greatest Common Divisor of 165, 272, 215, 853 is 1
