Given numbers are 120, 178, 161, 667
The list of prime factors of all numbers are
Prime factors of 120 are 2 x 2 x 2 x 3 x 5
Prime factors of 178 are 2 x 89
Prime factors of 161 are 7 x 23
Prime factors of 667 are 23 x 29
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 120, 178, 161, 667
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(120, 178) = 10680
GCD(120, 178) = ( 120 x 178 ) / 10680
= 120 / 178
= 120
Step2:
LCM(2, 161) = 322
GCD(2, 161) = ( 2 x 161 ) / 322
= 2 / 161
= 2
Step3:
LCM(1, 667) = 667
GCD(1, 667) = ( 1 x 667 ) / 667
= 1 / 667
= 1
So, Greatest Common Divisor of 120, 178, 161, 667 is 1
