Given numbers are 290, 178, 904, 909
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(290, 178) = 25810
GCD(290, 178) = ( 290 x 178 ) / 25810
= 290 / 178
= 290
Step2:
LCM(2, 904) = 904
GCD(2, 904) = ( 2 x 904 ) / 904
= 2 / 904
= 2
Step3:
LCM(2, 909) = 1818
GCD(2, 909) = ( 2 x 909 ) / 1818
= 2 / 909
= 2
So, Greatest Common Divisor of 290, 178, 904, 909 is 1
