Given numbers are 578, 427, 566, 780

The list of prime factors of all numbers are

Prime factors of 578 are 2 x 17 x 17

Prime factors of 427 are 7 x 61

Prime factors of 566 are 2 x 283

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 578, 427, 566, 780

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

Apply this formula for all numbers.

Step1:

LCM(578, 427) = 246806

GCD(578, 427) = ( 578 x 427 ) / 246806

= 578 / 427

= 578

Step2:

LCM(1, 566) = 566

GCD(1, 566) = ( 1 x 566 ) / 566

= 1 / 566

= 1

Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1

So, Greatest Common Divisor of 578, 427, 566, 780 is 1
