Given numbers are 905, 239, 790, 285
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(905, 239) = 216295
GCD(905, 239) = ( 905 x 239 ) / 216295
= 905 / 239
= 905
Step2:
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
= 1 / 790
= 1
Step3:
LCM(1, 285) = 285
GCD(1, 285) = ( 1 x 285 ) / 285
= 1 / 285
= 1
So, Greatest Common Divisor of 905, 239, 790, 285 is 1
