Given numbers are 178, 674, 432, 561

The list of prime factors of all numbers are

Prime factors of 178 are 2 x 89

Prime factors of 674 are 2 x 337

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 561 are 3 x 11 x 17

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

Given numbers are 178, 674, 432, 561

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

Apply this formula for all numbers.

Step1:

LCM(178, 674) = 59986

GCD(178, 674) = ( 178 x 674 ) / 59986

= 178 / 674

= 178

Step2:

LCM(2, 432) = 432

GCD(2, 432) = ( 2 x 432 ) / 432

= 2 / 432

= 2

Step3:

LCM(2, 561) = 1122

GCD(2, 561) = ( 2 x 561 ) / 1122

= 2 / 561

= 2

So, Greatest Common Divisor of 178, 674, 432, 561 is 1
