Given numbers are 878, 172, 663

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

Apply this formula for all numbers.

Step1:

LCM(878, 172) = 75508

GCD(878, 172) = ( 878 x 172 ) / 75508

= 878 / 172

= 878

Step2:

LCM(2, 663) = 1326

GCD(2, 663) = ( 2 x 663 ) / 1326

= 2 / 663

= 2

So, Greatest Common Divisor of 878, 172, 663 is 1
