Given numbers are 966, 687, 213, 644

The list of prime factors of all numbers are

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

Prime factors of 687 are 3 x 229

Prime factors of 213 are 3 x 71

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 966, 687, 213, 644

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

Apply this formula for all numbers.

Step1:

LCM(966, 687) = 221214

GCD(966, 687) = ( 966 x 687 ) / 221214

= 966 / 687

= 966

Step2:

LCM(3, 213) = 213

GCD(3, 213) = ( 3 x 213 ) / 213

= 3 / 213

= 3

Step3:

LCM(3, 644) = 1932

GCD(3, 644) = ( 3 x 644 ) / 1932

= 3 / 644

= 3

So, Greatest Common Divisor of 966, 687, 213, 644 is 1
