Therefore, GCD of numbers 28, 782, 383, 715 is 1

Given Input Data is 28, 782, 383, 715

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

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 782 is 2 x 17 x 23

Prime Factorization of 383 is 383

Prime Factorization of 715 is 5 x 11 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(28, 782) = 10948

GCD(28, 782) = ( 28 x 782 ) / 10948

GCD(28, 782) = 21896 / 10948

GCD(28, 782) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 383

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

LCM(2, 383) = 766

GCD(2, 383) = ( 2 x 383 ) / 766

GCD(2, 383) = 766 / 766

GCD(2, 383) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 715

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

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

GCD(1, 715) = 715 / 715

GCD(1, 715) = 1

GCD of 28, 782, 383, 715 is 1
