Given numbers are 685, 649, 826

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

Apply this formula for all numbers.

Step1:

LCM(685, 649) = 444565

GCD(685, 649) = ( 685 x 649 ) / 444565

= 685 / 649

= 685

Step2:

LCM(1, 826) = 826

GCD(1, 826) = ( 1 x 826 ) / 826

= 1 / 826

= 1

So, Greatest Common Divisor of 685, 649, 826 is 1
