Given numbers are 686, 661, 786

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

Apply this formula for all numbers.

Step1:

LCM(686, 661) = 453446

GCD(686, 661) = ( 686 x 661 ) / 453446

= 686 / 661

= 686

Step2:

LCM(1, 786) = 786

GCD(1, 786) = ( 1 x 786 ) / 786

= 1 / 786

= 1

So, Greatest Common Divisor of 686, 661, 786 is 1
