Therefore, GCD of numbers 77, 910, 398, 750 is 1

Given Input Data is 77, 910, 398, 750

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

Prime Factorization of 77 is 7 x 11

Prime Factorization of 910 is 2 x 5 x 7 x 13

Prime Factorization of 398 is 2 x 199

Prime Factorization of 750 is 2 x 3 x 5 x 5 x 5

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(77, 910) = 10010

GCD(77, 910) = ( 77 x 910 ) / 10010

GCD(77, 910) = 70070 / 10010

GCD(77, 910) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 398

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

LCM(7, 398) = 2786

GCD(7, 398) = ( 7 x 398 ) / 2786

GCD(7, 398) = 2786 / 2786

GCD(7, 398) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 750

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

LCM(1, 750) = 750

GCD(1, 750) = ( 1 x 750 ) / 750

GCD(1, 750) = 750 / 750

GCD(1, 750) = 1

GCD of 77, 910, 398, 750 is 1
