Given numbers are 456, 644, 555, 273

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 555 are 3 x 5 x 37

Prime factors of 273 are 3 x 7 x 13

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

Given numbers are 456, 644, 555, 273

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, 555) = 2220

GCD(4, 555) = ( 4 x 555 ) / 2220

= 4 / 555

= 4

Step3:

LCM(1, 273) = 273

GCD(1, 273) = ( 1 x 273 ) / 273

= 1 / 273

= 1

So, Greatest Common Divisor of 456, 644, 555, 273 is 1
