Given numbers are 891, 660, 551, 563

The list of prime factors of all numbers are

Prime factors of 891 are 3 x 3 x 3 x 3 x 11

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 551 are 19 x 29

Prime factors of 563 are 563

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

Given numbers are 891, 660, 551, 563

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

Apply this formula for all numbers.

Step1:

LCM(891, 660) = 17820

GCD(891, 660) = ( 891 x 660 ) / 17820

= 891 / 660

= 891

Step2:

LCM(33, 551) = 18183

GCD(33, 551) = ( 33 x 551 ) / 18183

= 33 / 551

= 33

Step3:

LCM(1, 563) = 563

GCD(1, 563) = ( 1 x 563 ) / 563

= 1 / 563

= 1

So, Greatest Common Divisor of 891, 660, 551, 563 is 1
