Therefore, GCD of numbers 66, 781, 750, 279 is 1

Given Input Data is 66, 781, 750, 279

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

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 781 is 11 x 71

Prime Factorization of 750 is 2 x 3 x 5 x 5 x 5

Prime Factorization of 279 is 3 x 3 x 31

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(66, 781) = 4686

GCD(66, 781) = ( 66 x 781 ) / 4686

GCD(66, 781) = 51546 / 4686

GCD(66, 781) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 750

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

LCM(11, 750) = 8250

GCD(11, 750) = ( 11 x 750 ) / 8250

GCD(11, 750) = 8250 / 8250

GCD(11, 750) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 279

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

LCM(1, 279) = 279

GCD(1, 279) = ( 1 x 279 ) / 279

GCD(1, 279) = 279 / 279

GCD(1, 279) = 1

GCD of 66, 781, 750, 279 is 1
