Given numbers are 438, 545, 475, 548

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 545 are 5 x 109

Prime factors of 475 are 5 x 5 x 19

Prime factors of 548 are 2 x 2 x 137

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

Given numbers are 438, 545, 475, 548

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

Apply this formula for all numbers.

Step1:

LCM(438, 545) = 238710

GCD(438, 545) = ( 438 x 545 ) / 238710

= 438 / 545

= 438

Step2:

LCM(1, 475) = 475

GCD(1, 475) = ( 1 x 475 ) / 475

= 1 / 475

= 1

Step3:

LCM(1, 548) = 548

GCD(1, 548) = ( 1 x 548 ) / 548

= 1 / 548

= 1

So, Greatest Common Divisor of 438, 545, 475, 548 is 1
