Given numbers are 245, 420, 289, 826

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 289 are 17 x 17

Prime factors of 826 are 2 x 7 x 59

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

Given numbers are 245, 420, 289, 826

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

Apply this formula for all numbers.

Step1:

LCM(245, 420) = 2940

GCD(245, 420) = ( 245 x 420 ) / 2940

= 245 / 420

= 245

Step2:

LCM(35, 289) = 10115

GCD(35, 289) = ( 35 x 289 ) / 10115

= 35 / 289

= 35

Step3:

LCM(1, 826) = 826

GCD(1, 826) = ( 1 x 826 ) / 826

= 1 / 826

= 1

So, Greatest Common Divisor of 245, 420, 289, 826 is 1
