Therefore, GCD of numbers 49, 28, 98 is 7

Given Input Data is 49, 28, 98

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

Prime Factorization of 49 is 7 x 7

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 98 is 2 x 7 x 7

Highest common occurrences in the given inputs are 7¹

Multiplying them we get the GCD as 7

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(49, 28) = 196

GCD(49, 28) = ( 49 x 28 ) / 196

GCD(49, 28) = 1372 / 196

GCD(49, 28) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 98

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

LCM(7, 98) = 98

GCD(7, 98) = ( 7 x 98 ) / 98

GCD(7, 98) = 686 / 98

GCD(7, 98) = 7

GCD of 49, 28, 98 is 7
