Therefore, GCD of numbers 416, 546, 157, 642 is 1

Given Input Data is 416, 546, 157, 642

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

Prime Factorization of 416 is 2 x 2 x 2 x 2 x 2 x 13

Prime Factorization of 546 is 2 x 3 x 7 x 13

Prime Factorization of 157 is 157

Prime Factorization of 642 is 2 x 3 x 107

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(416, 546) = 8736

GCD(416, 546) = ( 416 x 546 ) / 8736

GCD(416, 546) = 227136 / 8736

GCD(416, 546) = 26

Step2:

Here we consider the GCD from the above i.e. 26 as first number and the next as 157

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

LCM(26, 157) = 4082

GCD(26, 157) = ( 26 x 157 ) / 4082

GCD(26, 157) = 4082 / 4082

GCD(26, 157) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 642

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

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

GCD(1, 642) = 642 / 642

GCD(1, 642) = 1

GCD of 416, 546, 157, 642 is 1
