Given numbers are 309, 340, 781, 803

The list of prime factors of all numbers are

Prime factors of 309 are 3 x 103

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 781 are 11 x 71

Prime factors of 803 are 11 x 73

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

Given numbers are 309, 340, 781, 803

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

Apply this formula for all numbers.

Step1:

LCM(309, 340) = 105060

GCD(309, 340) = ( 309 x 340 ) / 105060

= 309 / 340

= 309

Step2:

LCM(1, 781) = 781

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

= 1 / 781

= 1

Step3:

LCM(1, 803) = 803

GCD(1, 803) = ( 1 x 803 ) / 803

= 1 / 803

= 1

So, Greatest Common Divisor of 309, 340, 781, 803 is 1
