Given numbers are 393, 305, 468, 686
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 305) = 119865
GCD(393, 305) = ( 393 x 305 ) / 119865
= 393 / 305
= 393
Step2:
LCM(1, 468) = 468
GCD(1, 468) = ( 1 x 468 ) / 468
= 1 / 468
= 1
Step3:
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
So, Greatest Common Divisor of 393, 305, 468, 686 is 1
