Given numbers are 305, 487, 572, 426

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 487 are 487

Prime factors of 572 are 2 x 2 x 11 x 13

Prime factors of 426 are 2 x 3 x 71

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

Given numbers are 305, 487, 572, 426

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

Apply this formula for all numbers.

Step1:

LCM(305, 487) = 148535

GCD(305, 487) = ( 305 x 487 ) / 148535

= 305 / 487

= 305

Step2:

LCM(1, 572) = 572

GCD(1, 572) = ( 1 x 572 ) / 572

= 1 / 572

= 1

Step3:

LCM(1, 426) = 426

GCD(1, 426) = ( 1 x 426 ) / 426

= 1 / 426

= 1

So, Greatest Common Divisor of 305, 487, 572, 426 is 1
