GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(713, 390) = 278070
GCD(713, 390) = ( 713 x 390 ) / 278070
= 713 / 390
= 713
Step2:
LCM(1, 419) = 419
GCD(1, 419) = ( 1 x 419 ) / 419
= 1 / 419
= 1
Step3:
LCM(1, 385) = 385
GCD(1, 385) = ( 1 x 385 ) / 385
= 1 / 385
= 1
So, Greatest Common Divisor of 713, 390, 419, 385 is 1
