Finding GCD of 77, 920, 287, 511 using Prime Factorization

Given Input Data is 77, 920, 287, 511

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

Prime Factorization of 77 is 7 x 11

Prime Factorization of 920 is 2 x 2 x 2 x 5 x 23

Prime Factorization of 287 is 7 x 41

Prime Factorization of 511 is 7 x 73

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

Finding GCD of 77, 920, 287, 511 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(77, 920) = 70840

GCD(77, 920) = ( 77 x 920 ) / 70840

GCD(77, 920) = 70840 / 70840

GCD(77, 920) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 287

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

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

GCD(1, 287) = 287 / 287

GCD(1, 287) = 1


Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 511

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

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

GCD(1, 511) = 511 / 511

GCD(1, 511) = 1

GCD of 77, 920, 287, 511 is 1
