Given numbers are 686, 710, 847, 685
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 710) = 243530
GCD(686, 710) = ( 686 x 710 ) / 243530
= 686 / 710
= 686
Step2:
LCM(2, 847) = 1694
GCD(2, 847) = ( 2 x 847 ) / 1694
= 2 / 847
= 2
Step3:
LCM(1, 685) = 685
GCD(1, 685) = ( 1 x 685 ) / 685
= 1 / 685
= 1
So, Greatest Common Divisor of 686, 710, 847, 685 is 1
