Given Input Data is 276, 918, 620

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

Prime Factorization of 276 is 2 x 2 x 3 x 23

Prime Factorization of 918 is 2 x 3 x 3 x 3 x 17

Prime Factorization of 620 is 2 x 2 x 5 x 31

Highest common occurrences in the given inputs are 2¹

Multiplying them we get the GCD as 2

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(276, 918) = 42228

GCD(276, 918) = ( 276 x 918 ) / 42228

GCD(276, 918) = 253368 / 42228

GCD(276, 918) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 620

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

LCM(6, 620) = 1860

GCD(6, 620) = ( 6 x 620 ) / 1860

GCD(6, 620) = 3720 / 1860

GCD(6, 620) = 2

GCD of 276, 918, 620 is 2
