GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(487, 206) = 100322
GCD(487, 206) = ( 487 x 206 ) / 100322
= 487 / 206
= 487
Step2:
LCM(1, 285) = 285
GCD(1, 285) = ( 1 x 285 ) / 285
= 1 / 285
= 1
Step3:
LCM(1, 945) = 945
GCD(1, 945) = ( 1 x 945 ) / 945
= 1 / 945
= 1
So, Greatest Common Divisor of 487, 206, 285, 945 is 1
