Given numbers are 161, 767, 990, 578

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

Prime factors of 767 are 13 x 59

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

Prime factors of 578 are 2 x 17 x 17

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

Given numbers are 161, 767, 990, 578

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

Apply this formula for all numbers.

Step1:

LCM(161, 767) = 123487

GCD(161, 767) = ( 161 x 767 ) / 123487

= 161 / 767

= 161

Step2:

LCM(1, 990) = 990

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

= 1 / 990

= 1

Step3:

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

= 1 / 578

= 1

So, Greatest Common Divisor of 161, 767, 990, 578 is 1
