So the Greatest Common Divisior 77, 55, 33 is 11.

Therefore, GCD of numbers 77, 55, 33 is 11

Given Input Data is 77, 55, 33

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 77 is 7 x 11

Prime Factorization of 55 is 5 x 11

Prime Factorization of 33 is 3 x 11

Highest common occurrences in the given inputs are 11¹

Multiplying them we get the GCD as 11

Step1:

Let's calculate the GCD of first two numbers

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

LCM(77, 55) = 385

GCD(77, 55) = ( 77 x 55 ) / 385

GCD(77, 55) = 4235 / 385

GCD(77, 55) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 33

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

LCM(11, 33) = 33

GCD(11, 33) = ( 11 x 33 ) / 33

GCD(11, 33) = 363 / 33

GCD(11, 33) = 11

GCD of 77, 55, 33 is 11
