Given numbers are 161, 638, 476, 252

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

Prime factors of 638 are 2 x 11 x 29

Prime factors of 476 are 2 x 2 x 7 x 17

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

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

Given numbers are 161, 638, 476, 252

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

Apply this formula for all numbers.

Step1:

LCM(161, 638) = 102718

GCD(161, 638) = ( 161 x 638 ) / 102718

= 161 / 638

= 161

Step2:

LCM(1, 476) = 476

GCD(1, 476) = ( 1 x 476 ) / 476

= 1 / 476

= 1

Step3:

LCM(1, 252) = 252

GCD(1, 252) = ( 1 x 252 ) / 252

= 1 / 252

= 1

So, Greatest Common Divisor of 161, 638, 476, 252 is 1
