The list of prime factors of all numbers are
Prime factors of 813 are 3 x 271
Prime factors of 251 are 251
Prime factors of 142 are 2 x 71
Prime factors of 256 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 813, 251, 142, 256
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(813, 251) = 204063
GCD(813, 251) = ( 813 x 251 ) / 204063
= 813 / 251
= 813
Step2:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
Step3:
LCM(1, 256) = 256
GCD(1, 256) = ( 1 x 256 ) / 256
= 1 / 256
= 1
So, Greatest Common Divisor of 813, 251, 142, 256 is 1
