Given numbers are 223, 644, 640, 916

The list of prime factors of all numbers are

Prime factors of 223 are 223

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

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 916 are 2 x 2 x 229

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

Given numbers are 223, 644, 640, 916

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

Apply this formula for all numbers.

Step1:

LCM(223, 644) = 143612

GCD(223, 644) = ( 223 x 644 ) / 143612

= 223 / 644

= 223

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 916) = 916

GCD(1, 916) = ( 1 x 916 ) / 916

= 1 / 916

= 1

So, Greatest Common Divisor of 223, 644, 640, 916 is 1
