Given numbers are 638, 170, 761, 252

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 170 are 2 x 5 x 17

Prime factors of 761 are 761

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 638, 170, 761, 252

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

Apply this formula for all numbers.

Step1:

LCM(638, 170) = 54230

GCD(638, 170) = ( 638 x 170 ) / 54230

= 638 / 170

= 638

Step2:

LCM(2, 761) = 1522

GCD(2, 761) = ( 2 x 761 ) / 1522

= 2 / 761

= 2

Step3:

LCM(1, 252) = 252

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

= 1 / 252

= 1

So, Greatest Common Divisor of 638, 170, 761, 252 is 1
