Given numbers are 450, 905, 165, 243
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(450, 905) = 81450
GCD(450, 905) = ( 450 x 905 ) / 81450
= 450 / 905
= 450
Step2:
LCM(5, 165) = 165
GCD(5, 165) = ( 5 x 165 ) / 165
= 5 / 165
= 5
Step3:
LCM(5, 243) = 1215
GCD(5, 243) = ( 5 x 243 ) / 1215
= 5 / 243
= 5
So, Greatest Common Divisor of 450, 905, 165, 243 is 1
