Therefore, GCD of numbers 55, 620, 700, 153 is 1

Given Input Data is 55, 620, 700, 153

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

Prime Factorization of 55 is 5 x 11

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

Prime Factorization of 700 is 2 x 2 x 5 x 5 x 7

Prime Factorization of 153 is 3 x 3 x 17

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(55, 620) = 6820

GCD(55, 620) = ( 55 x 620 ) / 6820

GCD(55, 620) = 34100 / 6820

GCD(55, 620) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 700

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

LCM(5, 700) = 700

GCD(5, 700) = ( 5 x 700 ) / 700

GCD(5, 700) = 3500 / 700

GCD(5, 700) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 153

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

LCM(5, 153) = 765

GCD(5, 153) = ( 5 x 153 ) / 765

GCD(5, 153) = 765 / 765

GCD(5, 153) = 1

GCD of 55, 620, 700, 153 is 1
