GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 585) = 390780
GCD(668, 585) = ( 668 x 585 ) / 390780
= 668 / 585
= 668
Step2:
LCM(1, 189) = 189
GCD(1, 189) = ( 1 x 189 ) / 189
= 1 / 189
= 1
Step3:
LCM(1, 206) = 206
GCD(1, 206) = ( 1 x 206 ) / 206
= 1 / 206
= 1
So, Greatest Common Divisor of 668, 585, 189, 206 is 1
