Given numbers are 161, 818, 796, 990

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

Prime factors of 818 are 2 x 409

Prime factors of 796 are 2 x 2 x 199

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

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

Given numbers are 161, 818, 796, 990

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

Apply this formula for all numbers.

Step1:

LCM(161, 818) = 131698

GCD(161, 818) = ( 161 x 818 ) / 131698

= 161 / 818

= 161

Step2:

LCM(1, 796) = 796

GCD(1, 796) = ( 1 x 796 ) / 796

= 1 / 796

= 1

Step3:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

So, Greatest Common Divisor of 161, 818, 796, 990 is 1
