Given Input Data is 745, 663, 62, 780

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

Prime Factorization of 745 is 5 x 149

Prime Factorization of 663 is 3 x 13 x 17

Prime Factorization of 62 is 2 x 31

Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13

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(745, 663) = 493935

GCD(745, 663) = ( 745 x 663 ) / 493935

GCD(745, 663) = 493935 / 493935

GCD(745, 663) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 62

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

LCM(1, 62) = 62

GCD(1, 62) = ( 1 x 62 ) / 62

GCD(1, 62) = 62 / 62

GCD(1, 62) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 780

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

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

GCD(1, 780) = 780 / 780

GCD(1, 780) = 1

GCD of 745, 663, 62, 780 is 1
