Therefore, GCD of numbers 777, 237, 260, 987 is 1

Given Input Data is 777, 237, 260, 987

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

Prime Factorization of 777 is 3 x 7 x 37

Prime Factorization of 237 is 3 x 79

Prime Factorization of 260 is 2 x 2 x 5 x 13

Prime Factorization of 987 is 3 x 7 x 47

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(777, 237) = 61383

GCD(777, 237) = ( 777 x 237 ) / 61383

GCD(777, 237) = 184149 / 61383

GCD(777, 237) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 260

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

LCM(3, 260) = 780

GCD(3, 260) = ( 3 x 260 ) / 780

GCD(3, 260) = 780 / 780

GCD(3, 260) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 987

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

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

GCD(1, 987) = 987 / 987

GCD(1, 987) = 1

GCD of 777, 237, 260, 987 is 1
