Given numbers are 686, 868, 913, 743

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(686, 868) = 42532

GCD(686, 868) = ( 686 x 868 ) / 42532

= 686 / 868

= 686

Step2:

LCM(14, 913) = 12782

GCD(14, 913) = ( 14 x 913 ) / 12782

= 14 / 913

= 14

Step3:

LCM(1, 743) = 743

GCD(1, 743) = ( 1 x 743 ) / 743

= 1 / 743

= 1

So, Greatest Common Divisor of 686, 868, 913, 743 is 1
