Given numbers are 945, 260, 457, 781

The list of prime factors of all numbers are

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 457 are 457

Prime factors of 781 are 11 x 71

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

Given numbers are 945, 260, 457, 781

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

Apply this formula for all numbers.

Step1:

LCM(945, 260) = 49140

GCD(945, 260) = ( 945 x 260 ) / 49140

= 945 / 260

= 945

Step2:

LCM(5, 457) = 2285

GCD(5, 457) = ( 5 x 457 ) / 2285

= 5 / 457

= 5

Step3:

LCM(1, 781) = 781

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

= 1 / 781

= 1

So, Greatest Common Divisor of 945, 260, 457, 781 is 1
