Given numbers are 479, 620, 780, 555

The list of prime factors of all numbers are

Prime factors of 479 are 479

Prime factors of 620 are 2 x 2 x 5 x 31

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

Prime factors of 555 are 3 x 5 x 37

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

Given numbers are 479, 620, 780, 555

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

Apply this formula for all numbers.

Step1:

LCM(479, 620) = 296980

GCD(479, 620) = ( 479 x 620 ) / 296980

= 479 / 620

= 479

Step2:

LCM(1, 780) = 780

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

= 1 / 780

= 1

Step3:

LCM(1, 555) = 555

GCD(1, 555) = ( 1 x 555 ) / 555

= 1 / 555

= 1

So, Greatest Common Divisor of 479, 620, 780, 555 is 1
