Given numbers are 305, 640, 696, 434

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 696 are 2 x 2 x 2 x 3 x 29

Prime factors of 434 are 2 x 7 x 31

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

Given numbers are 305, 640, 696, 434

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

Apply this formula for all numbers.

Step1:

LCM(305, 640) = 39040

GCD(305, 640) = ( 305 x 640 ) / 39040

= 305 / 640

= 305

Step2:

LCM(5, 696) = 3480

GCD(5, 696) = ( 5 x 696 ) / 3480

= 5 / 696

= 5

Step3:

LCM(1, 434) = 434

GCD(1, 434) = ( 1 x 434 ) / 434

= 1 / 434

= 1

So, Greatest Common Divisor of 305, 640, 696, 434 is 1
