Given numbers are 178, 130, 481, 742

The list of prime factors of all numbers are

Prime factors of 178 are 2 x 89

Prime factors of 130 are 2 x 5 x 13

Prime factors of 481 are 13 x 37

Prime factors of 742 are 2 x 7 x 53

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

Given numbers are 178, 130, 481, 742

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

Apply this formula for all numbers.

Step1:

LCM(178, 130) = 11570

GCD(178, 130) = ( 178 x 130 ) / 11570

= 178 / 130

= 178

Step2:

LCM(2, 481) = 962

GCD(2, 481) = ( 2 x 481 ) / 962

= 2 / 481

= 2

Step3:

LCM(1, 742) = 742

GCD(1, 742) = ( 1 x 742 ) / 742

= 1 / 742

= 1

So, Greatest Common Divisor of 178, 130, 481, 742 is 1
