Given numbers are 231, 287, 420, 866
The list of prime factors of all numbers are
Prime factors of 231 are 3 x 7 x 11
Prime factors of 287 are 7 x 41
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 866 are 2 x 433
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 231, 287, 420, 866
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(231, 287) = 9471
GCD(231, 287) = ( 231 x 287 ) / 9471
= 231 / 287
= 231
Step2:
LCM(7, 420) = 420
GCD(7, 420) = ( 7 x 420 ) / 420
= 7 / 420
= 7
Step3:
LCM(7, 866) = 6062
GCD(7, 866) = ( 7 x 866 ) / 6062
= 7 / 866
= 7
So, Greatest Common Divisor of 231, 287, 420, 866 is 1
