Given numbers are 305, 228, 507, 438

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 228 are 2 x 2 x 3 x 19

Prime factors of 507 are 3 x 13 x 13

Prime factors of 438 are 2 x 3 x 73

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

Given numbers are 305, 228, 507, 438

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

Apply this formula for all numbers.

Step1:

LCM(305, 228) = 69540

GCD(305, 228) = ( 305 x 228 ) / 69540

= 305 / 228

= 305

Step2:

LCM(1, 507) = 507

GCD(1, 507) = ( 1 x 507 ) / 507

= 1 / 507

= 1

Step3:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 305, 228, 507, 438 is 1
