So the Greatest Common Divisior 220, 650, 55, 764 is 1.

Therefore, GCD of numbers 220, 650, 55, 764 is 1

Given Input Data is 220, 650, 55, 764

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

Prime Factorization of 220 is 2 x 2 x 5 x 11

Prime Factorization of 650 is 2 x 5 x 5 x 13

Prime Factorization of 55 is 5 x 11

Prime Factorization of 764 is 2 x 2 x 191

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(220, 650) = 14300

GCD(220, 650) = ( 220 x 650 ) / 14300

GCD(220, 650) = 143000 / 14300

GCD(220, 650) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 55

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

LCM(10, 55) = 110

GCD(10, 55) = ( 10 x 55 ) / 110

GCD(10, 55) = 550 / 110

GCD(10, 55) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 764

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

LCM(5, 764) = 3820

GCD(5, 764) = ( 5 x 764 ) / 3820

GCD(5, 764) = 3820 / 3820

GCD(5, 764) = 1

GCD of 220, 650, 55, 764 is 1
