Given numbers are 305, 781, 652, 492

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 781 are 11 x 71

Prime factors of 652 are 2 x 2 x 163

Prime factors of 492 are 2 x 2 x 3 x 41

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

Given numbers are 305, 781, 652, 492

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

Apply this formula for all numbers.

Step1:

LCM(305, 781) = 238205

GCD(305, 781) = ( 305 x 781 ) / 238205

= 305 / 781

= 305

Step2:

LCM(1, 652) = 652

GCD(1, 652) = ( 1 x 652 ) / 652

= 1 / 652

= 1

Step3:

LCM(1, 492) = 492

GCD(1, 492) = ( 1 x 492 ) / 492

= 1 / 492

= 1

So, Greatest Common Divisor of 305, 781, 652, 492 is 1
