Given numbers are 830, 213, 820

The list of prime factors of all numbers are

Prime factors of 830 are 2 x 5 x 83

Prime factors of 213 are 3 x 71

Prime factors of 820 are 2 x 2 x 5 x 41

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

Given numbers are 830, 213, 820

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

Apply this formula for all numbers.

Step1:

LCM(830, 213) = 176790

GCD(830, 213) = ( 830 x 213 ) / 176790

= 830 / 213

= 830

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 830, 213, 820 is 1
