Given numbers are 781, 550, 345, 260

The list of prime factors of all numbers are

Prime factors of 781 are 11 x 71

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 345 are 3 x 5 x 23

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

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

Given numbers are 781, 550, 345, 260

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

Apply this formula for all numbers.

Step1:

LCM(781, 550) = 39050

GCD(781, 550) = ( 781 x 550 ) / 39050

= 781 / 550

= 781

Step2:

LCM(11, 345) = 3795

GCD(11, 345) = ( 11 x 345 ) / 3795

= 11 / 345

= 11

Step3:

LCM(1, 260) = 260

GCD(1, 260) = ( 1 x 260 ) / 260

= 1 / 260

= 1

So, Greatest Common Divisor of 781, 550, 345, 260 is 1
