Given numbers are 318, 755, 455, 945

The list of prime factors of all numbers are

Prime factors of 318 are 2 x 3 x 53

Prime factors of 755 are 5 x 151

Prime factors of 455 are 5 x 7 x 13

Prime factors of 945 are 3 x 3 x 3 x 5 x 7

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

Given numbers are 318, 755, 455, 945

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

Apply this formula for all numbers.

Step1:

LCM(318, 755) = 240090

GCD(318, 755) = ( 318 x 755 ) / 240090

= 318 / 755

= 318

Step2:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

Step3:

LCM(1, 945) = 945

GCD(1, 945) = ( 1 x 945 ) / 945

= 1 / 945

= 1

So, Greatest Common Divisor of 318, 755, 455, 945 is 1
