Given numbers are 305, 559, 781, 660

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 559 are 13 x 43

Prime factors of 781 are 11 x 71

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Given numbers are 305, 559, 781, 660

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

Apply this formula for all numbers.

Step1:

LCM(305, 559) = 170495

GCD(305, 559) = ( 305 x 559 ) / 170495

= 305 / 559

= 305

Step2:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 305, 559, 781, 660 is 1
