Given numbers are 810, 764, 921, 843
The list of prime factors of all numbers are
Prime factors of 810 are 2 x 3 x 3 x 3 x 3 x 5
Prime factors of 764 are 2 x 2 x 191
Prime factors of 921 are 3 x 307
Prime factors of 843 are 3 x 281
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 810, 764, 921, 843
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 764) = 309420
GCD(810, 764) = ( 810 x 764 ) / 309420
= 810 / 764
= 810
Step2:
LCM(2, 921) = 1842
GCD(2, 921) = ( 2 x 921 ) / 1842
= 2 / 921
= 2
Step3:
LCM(1, 843) = 843
GCD(1, 843) = ( 1 x 843 ) / 843
= 1 / 843
= 1
So, Greatest Common Divisor of 810, 764, 921, 843 is 1
