Given numbers are 231, 243, 159, 127
The list of prime factors of all numbers are
Prime factors of 231 are 3 x 7 x 11
Prime factors of 243 are 3 x 3 x 3 x 3 x 3
Prime factors of 159 are 3 x 53
Prime factors of 127 are 127
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 231, 243, 159, 127
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(231, 243) = 18711
GCD(231, 243) = ( 231 x 243 ) / 18711
= 231 / 243
= 231
Step2:
LCM(3, 159) = 159
GCD(3, 159) = ( 3 x 159 ) / 159
= 3 / 159
= 3
Step3:
LCM(3, 127) = 381
GCD(3, 127) = ( 3 x 127 ) / 381
= 3 / 127
= 3
So, Greatest Common Divisor of 231, 243, 159, 127 is 1
