Given numbers are 865, 158, 966, 668

The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 158 are 2 x 79

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

Prime factors of 668 are 2 x 2 x 167

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

Given numbers are 865, 158, 966, 668

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

Apply this formula for all numbers.

Step1:

LCM(865, 158) = 136670

GCD(865, 158) = ( 865 x 158 ) / 136670

= 865 / 158

= 865

Step2:

LCM(1, 966) = 966

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

= 1 / 966

= 1

Step3:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

So, Greatest Common Divisor of 865, 158, 966, 668 is 1
