Given numbers are 646, 900, 289, 550

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 900 are 2 x 2 x 3 x 3 x 5 x 5

Prime factors of 289 are 17 x 17

Prime factors of 550 are 2 x 5 x 5 x 11

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

Given numbers are 646, 900, 289, 550

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

Apply this formula for all numbers.

Step1:

LCM(646, 900) = 290700

GCD(646, 900) = ( 646 x 900 ) / 290700

= 646 / 900

= 646

Step2:

LCM(2, 289) = 578

GCD(2, 289) = ( 2 x 289 ) / 578

= 2 / 289

= 2

Step3:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

So, Greatest Common Divisor of 646, 900, 289, 550 is 1
