Given numbers are 878, 687, 65

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

Apply this formula for all numbers.

Step1:

LCM(878, 687) = 603186

GCD(878, 687) = ( 878 x 687 ) / 603186

= 878 / 687

= 878

Step2:

LCM(1, 65) = 65

GCD(1, 65) = ( 1 x 65 ) / 65

= 1 / 65

= 1

So, Greatest Common Divisor of 878, 687, 65 is 1
