Therefore, GCD of numbers 175, 546, 278, 661 is 1

Given Input Data is 175, 546, 278, 661

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

Prime Factorization of 175 is 5 x 5 x 7

Prime Factorization of 546 is 2 x 3 x 7 x 13

Prime Factorization of 278 is 2 x 139

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(175, 546) = 13650

GCD(175, 546) = ( 175 x 546 ) / 13650

GCD(175, 546) = 95550 / 13650

GCD(175, 546) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 278

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

LCM(7, 278) = 1946

GCD(7, 278) = ( 7 x 278 ) / 1946

GCD(7, 278) = 1946 / 1946

GCD(7, 278) = 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 175, 546, 278, 661 is 1
