Given numbers are 305, 484, 434, 644

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 484 are 2 x 2 x 11 x 11

Prime factors of 434 are 2 x 7 x 31

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 305, 484, 434, 644

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

Apply this formula for all numbers.

Step1:

LCM(305, 484) = 147620

GCD(305, 484) = ( 305 x 484 ) / 147620

= 305 / 484

= 305

Step2:

LCM(1, 434) = 434

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

= 1 / 434

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 305, 484, 434, 644 is 1
