Finding GCD of 853, 661, 61, 145 using Prime Factorization

Given Input Data is 853, 661, 61, 145

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

Prime Factorization of 853 is 853

Prime Factorization of 661 is 661

Prime Factorization of 61 is 61

Prime Factorization of 145 is 5 x 29

The above numbers do not have any common prime factor. So GCD is 1

Finding GCD of 853, 661, 61, 145 using LCM Formula

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(853, 661) = 563833

GCD(853, 661) = ( 853 x 661 ) / 563833

GCD(853, 661) = 563833 / 563833

GCD(853, 661) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 61

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

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

GCD(1, 61) = 61 / 61

GCD(1, 61) = 1


Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 145

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

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

GCD(1, 145) = 145 / 145

GCD(1, 145) = 1

GCD of 853, 661, 61, 145 is 1
