Given numbers are 611, 420, 407, 563

The list of prime factors of all numbers are

Prime factors of 611 are 13 x 47

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 407 are 11 x 37

Prime factors of 563 are 563

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

Given numbers are 611, 420, 407, 563

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

Apply this formula for all numbers.

Step1:

LCM(611, 420) = 256620

GCD(611, 420) = ( 611 x 420 ) / 256620

= 611 / 420

= 611

Step2:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

Step3:

LCM(1, 563) = 563

GCD(1, 563) = ( 1 x 563 ) / 563

= 1 / 563

= 1

So, Greatest Common Divisor of 611, 420, 407, 563 is 1
