Given numbers are 561, 810, 891, 236

The list of prime factors of all numbers are

Prime factors of 561 are 3 x 11 x 17

Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5

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

Prime factors of 236 are 2 x 2 x 59

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

Given numbers are 561, 810, 891, 236

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

Apply this formula for all numbers.

Step1:

LCM(561, 810) = 151470

GCD(561, 810) = ( 561 x 810 ) / 151470

= 561 / 810

= 561

Step2:

LCM(3, 891) = 891

GCD(3, 891) = ( 3 x 891 ) / 891

= 3 / 891

= 3

Step3:

LCM(3, 236) = 708

GCD(3, 236) = ( 3 x 236 ) / 708

= 3 / 236

= 3

So, Greatest Common Divisor of 561, 810, 891, 236 is 1
