Given numbers are 205, 256, 580
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(205, 256) = 52480
GCD(205, 256) = ( 205 x 256 ) / 52480
= 205 / 256
= 205
Step2:
LCM(1, 580) = 580
GCD(1, 580) = ( 1 x 580 ) / 580
= 1 / 580
= 1
So, Greatest Common Divisor of 205, 256, 580 is 1
