We found the divisors of 291, 665, 65, 402 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 291, 665, 65, 402 is 1.

Therefore, GCD of numbers 291, 665, 65, 402 is 1

Given Input Data is 291, 665, 65, 402

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

Prime Factorization of 291 is 3 x 97

Prime Factorization of 665 is 5 x 7 x 19

Prime Factorization of 65 is 5 x 13

Prime Factorization of 402 is 2 x 3 x 67

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(291, 665) = 193515

GCD(291, 665) = ( 291 x 665 ) / 193515

GCD(291, 665) = 193515 / 193515

GCD(291, 665) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 65

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

LCM(1, 65) = 65

GCD(1, 65) = ( 1 x 65 ) / 65

GCD(1, 65) = 65 / 65

GCD(1, 65) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 402

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

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

GCD(1, 402) = 402 / 402

GCD(1, 402) = 1

GCD of 291, 665, 65, 402 is 1
