Given numbers are 638, 115, 954, 570

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 115 are 5 x 23

Prime factors of 954 are 2 x 3 x 3 x 53

Prime factors of 570 are 2 x 3 x 5 x 19

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

Given numbers are 638, 115, 954, 570

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

Apply this formula for all numbers.

Step1:

LCM(638, 115) = 73370

GCD(638, 115) = ( 638 x 115 ) / 73370

= 638 / 115

= 638

Step2:

LCM(1, 954) = 954

GCD(1, 954) = ( 1 x 954 ) / 954

= 1 / 954

= 1

Step3:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

So, Greatest Common Divisor of 638, 115, 954, 570 is 1
