Given numbers are 686, 164, 138, 873

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

Apply this formula for all numbers.

Step1:

LCM(686, 164) = 56252

GCD(686, 164) = ( 686 x 164 ) / 56252

= 686 / 164

= 686

Step2:

LCM(2, 138) = 138

GCD(2, 138) = ( 2 x 138 ) / 138

= 2 / 138

= 2

Step3:

LCM(2, 873) = 1746

GCD(2, 873) = ( 2 x 873 ) / 1746

= 2 / 873

= 2

So, Greatest Common Divisor of 686, 164, 138, 873 is 1
