We found the divisors of 123, 970, 141, 860 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 123, 970, 141, 860 is 1.

Therefore, GCD of numbers 123, 970, 141, 860 is 1

Given Input Data is 123, 970, 141, 860

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

Prime Factorization of 123 is 3 x 41

Prime Factorization of 970 is 2 x 5 x 97

Prime Factorization of 141 is 3 x 47

Prime Factorization of 860 is 2 x 2 x 5 x 43

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(123, 970) = 119310

GCD(123, 970) = ( 123 x 970 ) / 119310

GCD(123, 970) = 119310 / 119310

GCD(123, 970) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 141

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

LCM(1, 141) = 141

GCD(1, 141) = ( 1 x 141 ) / 141

GCD(1, 141) = 141 / 141

GCD(1, 141) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 860

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

LCM(1, 860) = 860

GCD(1, 860) = ( 1 x 860 ) / 860

GCD(1, 860) = 860 / 860

GCD(1, 860) = 1

GCD of 123, 970, 141, 860 is 1
