Given numbers are 790, 865, 305, 308

The list of prime factors of all numbers are

Prime factors of 790 are 2 x 5 x 79

Prime factors of 865 are 5 x 173

Prime factors of 305 are 5 x 61

Prime factors of 308 are 2 x 2 x 7 x 11

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

Given numbers are 790, 865, 305, 308

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

Apply this formula for all numbers.

Step1:

LCM(790, 865) = 136670

GCD(790, 865) = ( 790 x 865 ) / 136670

= 790 / 865

= 790

Step2:

LCM(5, 305) = 305

GCD(5, 305) = ( 5 x 305 ) / 305

= 5 / 305

= 5

Step3:

LCM(5, 308) = 1540

GCD(5, 308) = ( 5 x 308 ) / 1540

= 5 / 308

= 5

So, Greatest Common Divisor of 790, 865, 305, 308 is 1
