Given Input Data is 771, 780, 366, 751

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

Prime Factorization of 771 is 3 x 257

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

Prime Factorization of 366 is 2 x 3 x 61

Prime Factorization of 751 is 751

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(771, 780) = 200460

GCD(771, 780) = ( 771 x 780 ) / 200460

GCD(771, 780) = 601380 / 200460

GCD(771, 780) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 366

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

LCM(3, 366) = 366

GCD(3, 366) = ( 3 x 366 ) / 366

GCD(3, 366) = 1098 / 366

GCD(3, 366) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 751

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

LCM(3, 751) = 2253

GCD(3, 751) = ( 3 x 751 ) / 2253

GCD(3, 751) = 2253 / 2253

GCD(3, 751) = 1

GCD of 771, 780, 366, 751 is 1
