Given numbers are 666, 742, 161, 805

The list of prime factors of all numbers are

Prime factors of 666 are 2 x 3 x 3 x 37

Prime factors of 742 are 2 x 7 x 53

Prime factors of 161 are 7 x 23

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 666, 742, 161, 805

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

Apply this formula for all numbers.

Step1:

LCM(666, 742) = 247086

GCD(666, 742) = ( 666 x 742 ) / 247086

= 666 / 742

= 666

Step2:

LCM(2, 161) = 322

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

= 2 / 161

= 2

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 666, 742, 161, 805 is 1
