Given numbers are 638, 765, 182, 905

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 182 are 2 x 7 x 13

Prime factors of 905 are 5 x 181

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

Given numbers are 638, 765, 182, 905

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

Apply this formula for all numbers.

Step1:

LCM(638, 765) = 488070

GCD(638, 765) = ( 638 x 765 ) / 488070

= 638 / 765

= 638

Step2:

LCM(1, 182) = 182

GCD(1, 182) = ( 1 x 182 ) / 182

= 1 / 182

= 1

Step3:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

So, Greatest Common Divisor of 638, 765, 182, 905 is 1
