Given numbers are 638, 532, 213, 471

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 532 are 2 x 2 x 7 x 19

Prime factors of 213 are 3 x 71

Prime factors of 471 are 3 x 157

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

Given numbers are 638, 532, 213, 471

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

Apply this formula for all numbers.

Step1:

LCM(638, 532) = 169708

GCD(638, 532) = ( 638 x 532 ) / 169708

= 638 / 532

= 638

Step2:

LCM(2, 213) = 426

GCD(2, 213) = ( 2 x 213 ) / 426

= 2 / 213

= 2

Step3:

LCM(1, 471) = 471

GCD(1, 471) = ( 1 x 471 ) / 471

= 1 / 471

= 1

So, Greatest Common Divisor of 638, 532, 213, 471 is 1
