Given numbers are 131, 423, 351, 123
The list of prime factors of all numbers are
Prime factors of 131 are 131
Prime factors of 423 are 3 x 3 x 47
Prime factors of 351 are 3 x 3 x 3 x 13
Prime factors of 123 are 3 x 41
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 131, 423, 351, 123
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(131, 423) = 55413
GCD(131, 423) = ( 131 x 423 ) / 55413
= 131 / 423
= 131
Step2:
LCM(1, 351) = 351
GCD(1, 351) = ( 1 x 351 ) / 351
= 1 / 351
= 1
Step3:
LCM(1, 123) = 123
GCD(1, 123) = ( 1 x 123 ) / 123
= 1 / 123
= 1
So, Greatest Common Divisor of 131, 423, 351, 123 is 1
