Given numbers are 420, 383, 291, 563

The list of prime factors of all numbers are

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

Prime factors of 383 are 383

Prime factors of 291 are 3 x 97

Prime factors of 563 are 563

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

Given numbers are 420, 383, 291, 563

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

Apply this formula for all numbers.

Step1:

LCM(420, 383) = 160860

GCD(420, 383) = ( 420 x 383 ) / 160860

= 420 / 383

= 420

Step2:

LCM(1, 291) = 291

GCD(1, 291) = ( 1 x 291 ) / 291

= 1 / 291

= 1

Step3:

LCM(1, 563) = 563

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

= 1 / 563

= 1

So, Greatest Common Divisor of 420, 383, 291, 563 is 1
