Given Input Data is 153, 187, 62, 661

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

Prime Factorization of 153 is 3 x 3 x 17

Prime Factorization of 187 is 11 x 17

Prime Factorization of 62 is 2 x 31

Prime Factorization of 661 is 661

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(153, 187) = 1683

GCD(153, 187) = ( 153 x 187 ) / 1683

GCD(153, 187) = 28611 / 1683

GCD(153, 187) = 17

Step2:

Here we consider the GCD from the above i.e. 17 as first number and the next as 62

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

LCM(17, 62) = 1054

GCD(17, 62) = ( 17 x 62 ) / 1054

GCD(17, 62) = 1054 / 1054

GCD(17, 62) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 661

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

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

GCD(1, 661) = 661 / 661

GCD(1, 661) = 1

GCD of 153, 187, 62, 661 is 1
