Given Input Data is 570, 894, 642

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

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 894 is 2 x 3 x 149

Prime Factorization of 642 is 2 x 3 x 107

Highest common occurrences in the given inputs are 2¹ x 3¹

Multiplying them we get the GCD as 6

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(570, 894) = 84930

GCD(570, 894) = ( 570 x 894 ) / 84930

GCD(570, 894) = 509580 / 84930

GCD(570, 894) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 642

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

LCM(6, 642) = 642

GCD(6, 642) = ( 6 x 642 ) / 642

GCD(6, 642) = 3852 / 642

GCD(6, 642) = 6

GCD of 570, 894, 642 is 6
