So the Greatest Common Divisior 759, 761, 621, 153 is 1.

Therefore, GCD of numbers 759, 761, 621, 153 is 1

Given Input Data is 759, 761, 621, 153

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

Prime Factorization of 759 is 3 x 11 x 23

Prime Factorization of 761 is 761

Prime Factorization of 621 is 3 x 3 x 3 x 23

Prime Factorization of 153 is 3 x 3 x 17

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(759, 761) = 577599

GCD(759, 761) = ( 759 x 761 ) / 577599

GCD(759, 761) = 577599 / 577599

GCD(759, 761) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 621

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

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

GCD(1, 621) = 621 / 621

GCD(1, 621) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 153

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

LCM(1, 153) = 153

GCD(1, 153) = ( 1 x 153 ) / 153

GCD(1, 153) = 153 / 153

GCD(1, 153) = 1

GCD of 759, 761, 621, 153 is 1
