Given numbers are 231, 169, 834, 145
The list of prime factors of all numbers are
Prime factors of 231 are 3 x 7 x 11
Prime factors of 169 are 13 x 13
Prime factors of 834 are 2 x 3 x 139
Prime factors of 145 are 5 x 29
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 231, 169, 834, 145
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(231, 169) = 39039
GCD(231, 169) = ( 231 x 169 ) / 39039
= 231 / 169
= 231
Step2:
LCM(1, 834) = 834
GCD(1, 834) = ( 1 x 834 ) / 834
= 1 / 834
= 1
Step3:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
So, Greatest Common Divisor of 231, 169, 834, 145 is 1
