Given numbers are 470, 178, 561, 144

The list of prime factors of all numbers are

Prime factors of 470 are 2 x 5 x 47

Prime factors of 178 are 2 x 89

Prime factors of 561 are 3 x 11 x 17

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

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

Given numbers are 470, 178, 561, 144

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

Apply this formula for all numbers.

Step1:

LCM(470, 178) = 41830

GCD(470, 178) = ( 470 x 178 ) / 41830

= 470 / 178

= 470

Step2:

LCM(2, 561) = 1122

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

= 2 / 561

= 2

Step3:

LCM(1, 144) = 144

GCD(1, 144) = ( 1 x 144 ) / 144

= 1 / 144

= 1

So, Greatest Common Divisor of 470, 178, 561, 144 is 1
