Given numbers are 318, 640, 243, 145

The list of prime factors of all numbers are

Prime factors of 318 are 2 x 3 x 53

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

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

Prime factors of 145 are 5 x 29

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

Given numbers are 318, 640, 243, 145

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

Apply this formula for all numbers.

Step1:

LCM(318, 640) = 101760

GCD(318, 640) = ( 318 x 640 ) / 101760

= 318 / 640

= 318

Step2:

LCM(2, 243) = 486

GCD(2, 243) = ( 2 x 243 ) / 486

= 2 / 243

= 2

Step3:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

So, Greatest Common Divisor of 318, 640, 243, 145 is 1
