Given numbers are 318, 308, 436, 643

The list of prime factors of all numbers are

Prime factors of 318 are 2 x 3 x 53

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

Prime factors of 436 are 2 x 2 x 109

Prime factors of 643 are 643

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

Given numbers are 318, 308, 436, 643

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

Apply this formula for all numbers.

Step1:

LCM(318, 308) = 48972

GCD(318, 308) = ( 318 x 308 ) / 48972

= 318 / 308

= 318

Step2:

LCM(2, 436) = 436

GCD(2, 436) = ( 2 x 436 ) / 436

= 2 / 436

= 2

Step3:

LCM(2, 643) = 1286

GCD(2, 643) = ( 2 x 643 ) / 1286

= 2 / 643

= 2

So, Greatest Common Divisor of 318, 308, 436, 643 is 1
