Given numbers are 591, 351, 396, 686
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(591, 351) = 69147
GCD(591, 351) = ( 591 x 351 ) / 69147
= 591 / 351
= 591
Step2:
LCM(3, 396) = 396
GCD(3, 396) = ( 3 x 396 ) / 396
= 3 / 396
= 3
Step3:
LCM(3, 686) = 2058
GCD(3, 686) = ( 3 x 686 ) / 2058
= 3 / 686
= 3
So, Greatest Common Divisor of 591, 351, 396, 686 is 1
