Given numbers are 168, 744, 905, 209
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(168, 744) = 5208
GCD(168, 744) = ( 168 x 744 ) / 5208
= 168 / 744
= 168
Step2:
LCM(24, 905) = 21720
GCD(24, 905) = ( 24 x 905 ) / 21720
= 24 / 905
= 24
Step3:
LCM(1, 209) = 209
GCD(1, 209) = ( 1 x 209 ) / 209
= 1 / 209
= 1
So, Greatest Common Divisor of 168, 744, 905, 209 is 1
