Given numbers are 130, 242, 620, 563

The list of prime factors of all numbers are

Prime factors of 130 are 2 x 5 x 13

Prime factors of 242 are 2 x 11 x 11

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

Prime factors of 563 are 563

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

Given numbers are 130, 242, 620, 563

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

Apply this formula for all numbers.

Step1:

LCM(130, 242) = 15730

GCD(130, 242) = ( 130 x 242 ) / 15730

= 130 / 242

= 130

Step2:

LCM(2, 620) = 620

GCD(2, 620) = ( 2 x 620 ) / 620

= 2 / 620

= 2

Step3:

LCM(2, 563) = 1126

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

= 2 / 563

= 2

So, Greatest Common Divisor of 130, 242, 620, 563 is 1
