Given numbers are 205, 603, 781, 225

The list of prime factors of all numbers are

Prime factors of 205 are 5 x 41

Prime factors of 603 are 3 x 3 x 67

Prime factors of 781 are 11 x 71

Prime factors of 225 are 3 x 3 x 5 x 5

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

Given numbers are 205, 603, 781, 225

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

Apply this formula for all numbers.

Step1:

LCM(205, 603) = 123615

GCD(205, 603) = ( 205 x 603 ) / 123615

= 205 / 603

= 205

Step2:

LCM(1, 781) = 781

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

= 1 / 781

= 1

Step3:

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

= 1 / 225

= 1

So, Greatest Common Divisor of 205, 603, 781, 225 is 1
