Given numbers are 161, 205, 672, 658

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

Prime factors of 205 are 5 x 41

Prime factors of 672 are 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime factors of 658 are 2 x 7 x 47

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

Given numbers are 161, 205, 672, 658

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

Apply this formula for all numbers.

Step1:

LCM(161, 205) = 33005

GCD(161, 205) = ( 161 x 205 ) / 33005

= 161 / 205

= 161

Step2:

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

= 1 / 672

= 1

Step3:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

So, Greatest Common Divisor of 161, 205, 672, 658 is 1
