Given numbers are 550, 920, 911, 455

The list of prime factors of all numbers are

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

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 911 are 911

Prime factors of 455 are 5 x 7 x 13

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

Given numbers are 550, 920, 911, 455

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

Apply this formula for all numbers.

Step1:

LCM(550, 920) = 50600

GCD(550, 920) = ( 550 x 920 ) / 50600

= 550 / 920

= 550

Step2:

LCM(10, 911) = 9110

GCD(10, 911) = ( 10 x 911 ) / 9110

= 10 / 911

= 10

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 550, 920, 911, 455 is 1
