Given numbers are 153, 252, 161, 123
The list of prime factors of all numbers are
Prime factors of 153 are 3 x 3 x 17
Prime factors of 252 are 2 x 2 x 3 x 3 x 7
Prime factors of 161 are 7 x 23
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 153, 252, 161, 123
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(153, 252) = 4284
GCD(153, 252) = ( 153 x 252 ) / 4284
= 153 / 252
= 153
Step2:
LCM(9, 161) = 1449
GCD(9, 161) = ( 9 x 161 ) / 1449
= 9 / 161
= 9
Step3:
LCM(1, 123) = 123
GCD(1, 123) = ( 1 x 123 ) / 123
= 1 / 123
= 1
So, Greatest Common Divisor of 153, 252, 161, 123 is 1
