Therefore, GCD of numbers 280, 483, 91, 560 is 7

Given Input Data is 280, 483, 91, 560

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

Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7

Prime Factorization of 483 is 3 x 7 x 23

Prime Factorization of 91 is 7 x 13

Prime Factorization of 560 is 2 x 2 x 2 x 2 x 5 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(280, 483) = 19320

GCD(280, 483) = ( 280 x 483 ) / 19320

GCD(280, 483) = 135240 / 19320

GCD(280, 483) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 91

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

LCM(7, 91) = 91

GCD(7, 91) = ( 7 x 91 ) / 91

GCD(7, 91) = 637 / 91

GCD(7, 91) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 560

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

LCM(7, 560) = 560

GCD(7, 560) = ( 7 x 560 ) / 560

GCD(7, 560) = 3920 / 560

GCD(7, 560) = 7

GCD of 280, 483, 91, 560 is 7
