GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(813, 682) = 554466
GCD(813, 682) = ( 813 x 682 ) / 554466
= 813 / 682
= 813
Step2:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
Step3:
LCM(1, 340) = 340
GCD(1, 340) = ( 1 x 340 ) / 340
= 1 / 340
= 1
So, Greatest Common Divisor of 813, 682, 391, 340 is 1
