Therefore, GCD of numbers 262, 270, 661 is 1

Given Input Data is 262, 270, 661

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

Prime Factorization of 262 is 2 x 131

Prime Factorization of 270 is 2 x 3 x 3 x 3 x 5

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(262, 270) = 35370

GCD(262, 270) = ( 262 x 270 ) / 35370

GCD(262, 270) = 70740 / 35370

GCD(262, 270) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 661

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

LCM(2, 661) = 1322

GCD(2, 661) = ( 2 x 661 ) / 1322

GCD(2, 661) = 1322 / 1322

GCD(2, 661) = 1

GCD of 262, 270, 661 is 1
