Given numbers are 820, 425, 407

The list of prime factors of all numbers are

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

Prime factors of 425 are 5 x 5 x 17

Prime factors of 407 are 11 x 37

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

Given numbers are 820, 425, 407

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

Apply this formula for all numbers.

Step1:

LCM(820, 425) = 69700

GCD(820, 425) = ( 820 x 425 ) / 69700

= 820 / 425

= 820

Step2:

LCM(5, 407) = 2035

GCD(5, 407) = ( 5 x 407 ) / 2035

= 5 / 407

= 5

So, Greatest Common Divisor of 820, 425, 407 is 1
