Given numbers are 105, 638, 473, 755

The list of prime factors of all numbers are

Prime factors of 105 are 3 x 5 x 7

Prime factors of 638 are 2 x 11 x 29

Prime factors of 473 are 11 x 43

Prime factors of 755 are 5 x 151

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

Given numbers are 105, 638, 473, 755

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

Apply this formula for all numbers.

Step1:

LCM(105, 638) = 66990

GCD(105, 638) = ( 105 x 638 ) / 66990

= 105 / 638

= 105

Step2:

LCM(1, 473) = 473

GCD(1, 473) = ( 1 x 473 ) / 473

= 1 / 473

= 1

Step3:

LCM(1, 755) = 755

GCD(1, 755) = ( 1 x 755 ) / 755

= 1 / 755

= 1

So, Greatest Common Divisor of 105, 638, 473, 755 is 1
