Given numbers are 440, 145, 661, 318

The list of prime factors of all numbers are

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 145 are 5 x 29

Prime factors of 661 are 661

Prime factors of 318 are 2 x 3 x 53

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

Given numbers are 440, 145, 661, 318

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

Apply this formula for all numbers.

Step1:

LCM(440, 145) = 12760

GCD(440, 145) = ( 440 x 145 ) / 12760

= 440 / 145

= 440

Step2:

LCM(5, 661) = 3305

GCD(5, 661) = ( 5 x 661 ) / 3305

= 5 / 661

= 5

Step3:

LCM(1, 318) = 318

GCD(1, 318) = ( 1 x 318 ) / 318

= 1 / 318

= 1

So, Greatest Common Divisor of 440, 145, 661, 318 is 1
