Given numbers are 165, 341, 822, 644

The list of prime factors of all numbers are

Prime factors of 165 are 3 x 5 x 11

Prime factors of 341 are 11 x 31

Prime factors of 822 are 2 x 3 x 137

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 165, 341, 822, 644

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

Apply this formula for all numbers.

Step1:

LCM(165, 341) = 5115

GCD(165, 341) = ( 165 x 341 ) / 5115

= 165 / 341

= 165

Step2:

LCM(11, 822) = 9042

GCD(11, 822) = ( 11 x 822 ) / 9042

= 11 / 822

= 11

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 165, 341, 822, 644 is 1
