Given numbers are 545, 178, 392, 480

The list of prime factors of all numbers are

Prime factors of 545 are 5 x 109

Prime factors of 178 are 2 x 89

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 545, 178, 392, 480

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

Apply this formula for all numbers.

Step1:

LCM(545, 178) = 97010

GCD(545, 178) = ( 545 x 178 ) / 97010

= 545 / 178

= 545

Step2:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

Step3:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

So, Greatest Common Divisor of 545, 178, 392, 480 is 1
