Given numbers are 551, 815, 470, 165

The list of prime factors of all numbers are

Prime factors of 551 are 19 x 29

Prime factors of 815 are 5 x 163

Prime factors of 470 are 2 x 5 x 47

Prime factors of 165 are 3 x 5 x 11

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

Given numbers are 551, 815, 470, 165

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

Apply this formula for all numbers.

Step1:

LCM(551, 815) = 449065

GCD(551, 815) = ( 551 x 815 ) / 449065

= 551 / 815

= 551

Step2:

LCM(1, 470) = 470

GCD(1, 470) = ( 1 x 470 ) / 470

= 1 / 470

= 1

Step3:

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

= 1 / 165

= 1

So, Greatest Common Divisor of 551, 815, 470, 165 is 1
