Given numbers are 273, 490, 780, 793

The list of prime factors of all numbers are

Prime factors of 273 are 3 x 7 x 13

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 793 are 13 x 61

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

Given numbers are 273, 490, 780, 793

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

Apply this formula for all numbers.

Step1:

LCM(273, 490) = 19110

GCD(273, 490) = ( 273 x 490 ) / 19110

= 273 / 490

= 273

Step2:

LCM(7, 780) = 5460

GCD(7, 780) = ( 7 x 780 ) / 5460

= 7 / 780

= 7

Step3:

LCM(1, 793) = 793

GCD(1, 793) = ( 1 x 793 ) / 793

= 1 / 793

= 1

So, Greatest Common Divisor of 273, 490, 780, 793 is 1
