Given numbers are 558, 644, 161, 667

The list of prime factors of all numbers are

Prime factors of 558 are 2 x 3 x 3 x 31

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

Prime factors of 161 are 7 x 23

Prime factors of 667 are 23 x 29

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

Given numbers are 558, 644, 161, 667

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

Apply this formula for all numbers.

Step1:

LCM(558, 644) = 179676

GCD(558, 644) = ( 558 x 644 ) / 179676

= 558 / 644

= 558

Step2:

LCM(2, 161) = 322

GCD(2, 161) = ( 2 x 161 ) / 322

= 2 / 161

= 2

Step3:

LCM(1, 667) = 667

GCD(1, 667) = ( 1 x 667 ) / 667

= 1 / 667

= 1

So, Greatest Common Divisor of 558, 644, 161, 667 is 1
