Given numbers are 647, 668, 966, 240

The list of prime factors of all numbers are

Prime factors of 647 are 647

Prime factors of 668 are 2 x 2 x 167

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

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 647, 668, 966, 240

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

Apply this formula for all numbers.

Step1:

LCM(647, 668) = 432196

GCD(647, 668) = ( 647 x 668 ) / 432196

= 647 / 668

= 647

Step2:

LCM(1, 966) = 966

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

= 1 / 966

= 1

Step3:

LCM(1, 240) = 240

GCD(1, 240) = ( 1 x 240 ) / 240

= 1 / 240

= 1

So, Greatest Common Divisor of 647, 668, 966, 240 is 1
