Given numbers are 305, 513, 134, 561

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 513 are 3 x 3 x 3 x 19

Prime factors of 134 are 2 x 67

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 305, 513, 134, 561

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

Apply this formula for all numbers.

Step1:

LCM(305, 513) = 156465

GCD(305, 513) = ( 305 x 513 ) / 156465

= 305 / 513

= 305

Step2:

LCM(1, 134) = 134

GCD(1, 134) = ( 1 x 134 ) / 134

= 1 / 134

= 1

Step3:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 305, 513, 134, 561 is 1
