Given numbers are 165, 552, 675, 643

The list of prime factors of all numbers are

Prime factors of 165 are 3 x 5 x 11

Prime factors of 552 are 2 x 2 x 2 x 3 x 23

Prime factors of 675 are 3 x 3 x 3 x 5 x 5

Prime factors of 643 are 643

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

Given numbers are 165, 552, 675, 643

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

Apply this formula for all numbers.

Step1:

LCM(165, 552) = 30360

GCD(165, 552) = ( 165 x 552 ) / 30360

= 165 / 552

= 165

Step2:

LCM(3, 675) = 675

GCD(3, 675) = ( 3 x 675 ) / 675

= 3 / 675

= 3

Step3:

LCM(3, 643) = 1929

GCD(3, 643) = ( 3 x 643 ) / 1929

= 3 / 643

= 3

So, Greatest Common Divisor of 165, 552, 675, 643 is 1
