Given numbers are 385, 125, 285, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(385, 125) = 9625
GCD(385, 125) = ( 385 x 125 ) / 9625
= 385 / 125
= 385
Step2:
LCM(5, 285) = 285
GCD(5, 285) = ( 5 x 285 ) / 285
= 5 / 285
= 5
Step3:
LCM(5, 809) = 4045
GCD(5, 809) = ( 5 x 809 ) / 4045
= 5 / 809
= 5
So, Greatest Common Divisor of 385, 125, 285, 809 is 1
