The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 954 are 2 x 3 x 3 x 53

Prime factors of 206 are 2 x 103

Prime factors of 731 are 17 x 43

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

Given numbers are 645, 954, 206, 731

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

Apply this formula for all numbers.

Step1:

LCM(645, 954) = 205110

GCD(645, 954) = ( 645 x 954 ) / 205110

= 645 / 954

= 645

Step2:

LCM(3, 206) = 618

GCD(3, 206) = ( 3 x 206 ) / 618

= 3 / 206

= 3

Step3:

LCM(1, 731) = 731

GCD(1, 731) = ( 1 x 731 ) / 731

= 1 / 731

= 1

So, Greatest Common Divisor of 645, 954, 206, 731 is 1
