Given numbers are 233, 217, 320, 644

The list of prime factors of all numbers are

Prime factors of 233 are 233

Prime factors of 217 are 7 x 31

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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 233, 217, 320, 644

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

Apply this formula for all numbers.

Step1:

LCM(233, 217) = 50561

GCD(233, 217) = ( 233 x 217 ) / 50561

= 233 / 217

= 233

Step2:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 233, 217, 320, 644 is 1
