Given numbers are 456, 644, 559, 223

The list of prime factors of all numbers are

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

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

Prime factors of 559 are 13 x 43

Prime factors of 223 are 223

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

Given numbers are 456, 644, 559, 223

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

Apply this formula for all numbers.

Step1:

LCM(456, 644) = 73416

GCD(456, 644) = ( 456 x 644 ) / 73416

= 456 / 644

= 456

Step2:

LCM(4, 559) = 2236

GCD(4, 559) = ( 4 x 559 ) / 2236

= 4 / 559

= 4

Step3:

LCM(1, 223) = 223

GCD(1, 223) = ( 1 x 223 ) / 223

= 1 / 223

= 1

So, Greatest Common Divisor of 456, 644, 559, 223 is 1
