Given numbers are 830, 823, 225, 243

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 823 are 823

Prime factors of 225 are 3 x 3 x 5 x 5

Prime factors of 243 are 3 x 3 x 3 x 3 x 3

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

Given numbers are 830, 823, 225, 243

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

Apply this formula for all numbers.

Step1:

LCM(830, 823) = 683090

GCD(830, 823) = ( 830 x 823 ) / 683090

= 830 / 823

= 830

Step2:

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

= 1 / 225

= 1

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 830, 823, 225, 243 is 1
