Given numbers are 645, 410, 884, 550

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 410 are 2 x 5 x 41

Prime factors of 884 are 2 x 2 x 13 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 645, 410, 884, 550

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

Apply this formula for all numbers.

Step1:

LCM(645, 410) = 52890

GCD(645, 410) = ( 645 x 410 ) / 52890

= 645 / 410

= 645

Step2:

LCM(5, 884) = 4420

GCD(5, 884) = ( 5 x 884 ) / 4420

= 5 / 884

= 5

Step3:

LCM(1, 550) = 550

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

= 1 / 550

= 1

So, Greatest Common Divisor of 645, 410, 884, 550 is 1
