Given numbers are 638, 644, 633, 462

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 633 are 3 x 211

Prime factors of 462 are 2 x 3 x 7 x 11

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

Given numbers are 638, 644, 633, 462

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

Apply this formula for all numbers.

Step1:

LCM(638, 644) = 205436

GCD(638, 644) = ( 638 x 644 ) / 205436

= 638 / 644

= 638

Step2:

LCM(2, 633) = 1266

GCD(2, 633) = ( 2 x 633 ) / 1266

= 2 / 633

= 2

Step3:

LCM(1, 462) = 462

GCD(1, 462) = ( 1 x 462 ) / 462

= 1 / 462

= 1

So, Greatest Common Divisor of 638, 644, 633, 462 is 1
