Make use of GCD Calculator to determine the Greatest Common Divisor of 77, 920, 287, 511 i.e. 1 largest integer that divides all the numbers equally.
GCD of 77, 920, 287, 511 is 1
GCD(77, 920, 287, 511) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 77, 920, 287, 511 is 1
GCD(77, 920, 287, 511) = 1
Given Input numbers are 77, 920, 287, 511
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 77

1, 7, 73, 511
Greatest Common Divisior
We found the divisors of 77, 920, 287, 511 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 77, 920, 287, 511 is 1.
Therefore, GCD of numbers 77, 920, 287, 511 is 1
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
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
