Given numbers are 830, 562, 426, 815

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 562 are 2 x 281

Prime factors of 426 are 2 x 3 x 71

Prime factors of 815 are 5 x 163

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

Given numbers are 830, 562, 426, 815

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

Apply this formula for all numbers.

Step1:

LCM(830, 562) = 233230

GCD(830, 562) = ( 830 x 562 ) / 233230

= 830 / 562

= 830

Step2:

LCM(2, 426) = 426

GCD(2, 426) = ( 2 x 426 ) / 426

= 2 / 426

= 2

Step3:

LCM(2, 815) = 1630

GCD(2, 815) = ( 2 x 815 ) / 1630

= 2 / 815

= 2

So, Greatest Common Divisor of 830, 562, 426, 815 is 1
