Given numbers are 161, 138, 899, 459
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 138) = 966
GCD(161, 138) = ( 161 x 138 ) / 966
= 161 / 138
= 161
Step2:
LCM(23, 899) = 20677
GCD(23, 899) = ( 23 x 899 ) / 20677
= 23 / 899
= 23
Step3:
LCM(1, 459) = 459
GCD(1, 459) = ( 1 x 459 ) / 459
= 1 / 459
= 1
So, Greatest Common Divisor of 161, 138, 899, 459 is 1
