Given numbers are 686, 251, 976

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

Apply this formula for all numbers.

Step1:

LCM(686, 251) = 172186

GCD(686, 251) = ( 686 x 251 ) / 172186

= 686 / 251

= 686

Step2:

LCM(1, 976) = 976

GCD(1, 976) = ( 1 x 976 ) / 976

= 1 / 976

= 1

So, Greatest Common Divisor of 686, 251, 976 is 1
