Given numbers are 645, 781, 966, 270

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 781 are 11 x 71

Prime factors of 966 are 2 x 3 x 7 x 23

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

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

Given numbers are 645, 781, 966, 270

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

Apply this formula for all numbers.

Step1:

LCM(645, 781) = 503745

GCD(645, 781) = ( 645 x 781 ) / 503745

= 645 / 781

= 645

Step2:

LCM(1, 966) = 966

GCD(1, 966) = ( 1 x 966 ) / 966

= 1 / 966

= 1

Step3:

LCM(1, 270) = 270

GCD(1, 270) = ( 1 x 270 ) / 270

= 1 / 270

= 1

So, Greatest Common Divisor of 645, 781, 966, 270 is 1
