Given numbers are 142, 161, 209, 505

The list of prime factors of all numbers are

Prime factors of 142 are 2 x 71

Prime factors of 161 are 7 x 23

Prime factors of 209 are 11 x 19

Prime factors of 505 are 5 x 101

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

Given numbers are 142, 161, 209, 505

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

Apply this formula for all numbers.

Step1:

LCM(142, 161) = 22862

GCD(142, 161) = ( 142 x 161 ) / 22862

= 142 / 161

= 142

Step2:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

Step3:

LCM(1, 505) = 505

GCD(1, 505) = ( 1 x 505 ) / 505

= 1 / 505

= 1

So, Greatest Common Divisor of 142, 161, 209, 505 is 1
