The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 657 are 3 x 3 x 73

Prime factors of 946 are 2 x 11 x 43

Prime factors of 955 are 5 x 191

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

Given numbers are 645, 657, 946, 955

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

Apply this formula for all numbers.

Step1:

LCM(645, 657) = 141255

GCD(645, 657) = ( 645 x 657 ) / 141255

= 645 / 657

= 645

Step2:

LCM(3, 946) = 2838

GCD(3, 946) = ( 3 x 946 ) / 2838

= 3 / 946

= 3

Step3:

LCM(1, 955) = 955

GCD(1, 955) = ( 1 x 955 ) / 955

= 1 / 955

= 1

So, Greatest Common Divisor of 645, 657, 946, 955 is 1
