Given numbers are 55, 89, 68

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

Apply this formula for all numbers.

Step1:

LCM(55, 89) = 4895

GCD(55, 89) = ( 55 x 89 ) / 4895

= 55 / 89

= 55

Step2:

LCM(1, 68) = 68

GCD(1, 68) = ( 1 x 68 ) / 68

= 1 / 68

= 1

So, Greatest Common Divisor of 55, 89, 68 is 1
