Given numbers are 650, 820, 289

The list of prime factors of all numbers are

Prime factors of 650 are 2 x 5 x 5 x 13

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

Prime factors of 289 are 17 x 17

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

Given numbers are 650, 820, 289

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

Apply this formula for all numbers.

Step1:

LCM(650, 820) = 53300

GCD(650, 820) = ( 650 x 820 ) / 53300

= 650 / 820

= 650

Step2:

LCM(10, 289) = 2890

GCD(10, 289) = ( 10 x 289 ) / 2890

= 10 / 289

= 10

So, Greatest Common Divisor of 650, 820, 289 is 1
