Given numbers are 830, 134, 686, 563

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 134 are 2 x 67

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 563 are 563

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

Given numbers are 830, 134, 686, 563

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

Apply this formula for all numbers.

Step1:

LCM(830, 134) = 55610

GCD(830, 134) = ( 830 x 134 ) / 55610

= 830 / 134

= 830

Step2:

LCM(2, 686) = 686

GCD(2, 686) = ( 2 x 686 ) / 686

= 2 / 686

= 2

Step3:

LCM(2, 563) = 1126

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

= 2 / 563

= 2

So, Greatest Common Divisor of 830, 134, 686, 563 is 1
