Given numbers are 273, 644, 405, 492

The list of prime factors of all numbers are

Prime factors of 273 are 3 x 7 x 13

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

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 492 are 2 x 2 x 3 x 41

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

Given numbers are 273, 644, 405, 492

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

Apply this formula for all numbers.

Step1:

LCM(273, 644) = 25116

GCD(273, 644) = ( 273 x 644 ) / 25116

= 273 / 644

= 273

Step2:

LCM(7, 405) = 2835

GCD(7, 405) = ( 7 x 405 ) / 2835

= 7 / 405

= 7

Step3:

LCM(1, 492) = 492

GCD(1, 492) = ( 1 x 492 ) / 492

= 1 / 492

= 1

So, Greatest Common Divisor of 273, 644, 405, 492 is 1
