We found the divisors of 64, 62, 25, 19 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 64, 62, 25, 19 is 1.

Therefore, GCD of numbers 64, 62, 25, 19 is 1

Given Input Data is 64, 62, 25, 19

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

Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 62 is 2 x 31

Prime Factorization of 25 is 5 x 5

Prime Factorization of 19 is 19

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(64, 62) = 1984

GCD(64, 62) = ( 64 x 62 ) / 1984

GCD(64, 62) = 3968 / 1984

GCD(64, 62) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 25

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

LCM(2, 25) = 50

GCD(2, 25) = ( 2 x 25 ) / 50

GCD(2, 25) = 50 / 50

GCD(2, 25) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 19

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

LCM(1, 19) = 19

GCD(1, 19) = ( 1 x 19 ) / 19

GCD(1, 19) = 19 / 19

GCD(1, 19) = 1

GCD of 64, 62, 25, 19 is 1
