Given numbers are 427, 481, 273, 780

The list of prime factors of all numbers are

Prime factors of 427 are 7 x 61

Prime factors of 481 are 13 x 37

Prime factors of 273 are 3 x 7 x 13

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

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

Given numbers are 427, 481, 273, 780

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

Apply this formula for all numbers.

Step1:

LCM(427, 481) = 205387

GCD(427, 481) = ( 427 x 481 ) / 205387

= 427 / 481

= 427

Step2:

LCM(1, 273) = 273

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

= 1 / 273

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 427, 481, 273, 780 is 1
