We found the divisors of 786, 757, 77, 261 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 786, 757, 77, 261 is 1.

Therefore, GCD of numbers 786, 757, 77, 261 is 1

Given Input Data is 786, 757, 77, 261

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

Prime Factorization of 786 is 2 x 3 x 131

Prime Factorization of 757 is 757

Prime Factorization of 77 is 7 x 11

Prime Factorization of 261 is 3 x 3 x 29

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(786, 757) = 595002

GCD(786, 757) = ( 786 x 757 ) / 595002

GCD(786, 757) = 595002 / 595002

GCD(786, 757) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 77

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

LCM(1, 77) = 77

GCD(1, 77) = ( 1 x 77 ) / 77

GCD(1, 77) = 77 / 77

GCD(1, 77) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 261

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

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

GCD(1, 261) = 261 / 261

GCD(1, 261) = 1

GCD of 786, 757, 77, 261 is 1
