So the Greatest Common Divisior 745, 666, 66 is 1.

Therefore, GCD of numbers 745, 666, 66 is 1

Given Input Data is 745, 666, 66

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

Prime Factorization of 745 is 5 x 149

Prime Factorization of 666 is 2 x 3 x 3 x 37

Prime Factorization of 66 is 2 x 3 x 11

The above numbers do not have any common prime factor. So GCD is 1

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(745, 666) = 496170

GCD(745, 666) = ( 745 x 666 ) / 496170

GCD(745, 666) = 496170 / 496170

GCD(745, 666) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 66

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

LCM(1, 66) = 66

GCD(1, 66) = ( 1 x 66 ) / 66

GCD(1, 66) = 66 / 66

GCD(1, 66) = 1

GCD of 745, 666, 66 is 1
