Therefore, GCD of numbers 68, 624, 155, 672 is 1

Given Input Data is 68, 624, 155, 672

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

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 624 is 2 x 2 x 2 x 2 x 3 x 13

Prime Factorization of 155 is 5 x 31

Prime Factorization of 672 is 2 x 2 x 2 x 2 x 2 x 3 x 7

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(68, 624) = 10608

GCD(68, 624) = ( 68 x 624 ) / 10608

GCD(68, 624) = 42432 / 10608

GCD(68, 624) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 155

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

LCM(4, 155) = 620

GCD(4, 155) = ( 4 x 155 ) / 620

GCD(4, 155) = 620 / 620

GCD(4, 155) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 672

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

LCM(1, 672) = 672

GCD(1, 672) = ( 1 x 672 ) / 672

GCD(1, 672) = 672 / 672

GCD(1, 672) = 1

GCD of 68, 624, 155, 672 is 1
