Given numbers are 306, 686, 139, 285
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(306, 686) = 104958
GCD(306, 686) = ( 306 x 686 ) / 104958
= 306 / 686
= 306
Step2:
LCM(2, 139) = 278
GCD(2, 139) = ( 2 x 139 ) / 278
= 2 / 139
= 2
Step3:
LCM(1, 285) = 285
GCD(1, 285) = ( 1 x 285 ) / 285
= 1 / 285
= 1
So, Greatest Common Divisor of 306, 686, 139, 285 is 1
