GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(285, 915) = 17385
GCD(285, 915) = ( 285 x 915 ) / 17385
= 285 / 915
= 285
Step2:
LCM(15, 904) = 13560
GCD(15, 904) = ( 15 x 904 ) / 13560
= 15 / 904
= 15
Step3:
LCM(1, 346) = 346
GCD(1, 346) = ( 1 x 346 ) / 346
= 1 / 346
= 1
So, Greatest Common Divisor of 285, 915, 904, 346 is 1
