Given numbers are 612, 554, 780, 563

The list of prime factors of all numbers are

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 554 are 2 x 277

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

Prime factors of 563 are 563

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

Given numbers are 612, 554, 780, 563

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

Apply this formula for all numbers.

Step1:

LCM(612, 554) = 169524

GCD(612, 554) = ( 612 x 554 ) / 169524

= 612 / 554

= 612

Step2:

LCM(2, 780) = 780

GCD(2, 780) = ( 2 x 780 ) / 780

= 2 / 780

= 2

Step3:

LCM(2, 563) = 1126

GCD(2, 563) = ( 2 x 563 ) / 1126

= 2 / 563

= 2

So, Greatest Common Divisor of 612, 554, 780, 563 is 1
