GCD of 280, 167, 520, 778 is 1
GCD(280, 167, 520, 778) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 280, 167, 520, 778 is 1
GCD(280, 167, 520, 778) = 1
Given Input numbers are 280, 167, 520, 778
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 389, 778
Greatest Common Divisior
We found the divisors of 280, 167, 520, 778 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 280, 167, 520, 778 is 1.
Therefore, GCD of numbers 280, 167, 520, 778 is 1
Given Input Data is 280, 167, 520, 778
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7
Prime Factorization of 167 is 167
Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13
Prime Factorization of 778 is 2 x 389
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(280, 167) = 46760
GCD(280, 167) = ( 280 x 167 ) / 46760
GCD(280, 167) = 46760 / 46760
GCD(280, 167) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 520
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 520) = 520
GCD(1, 520) = ( 1 x 520 ) / 520
GCD(1, 520) = 520 / 520
GCD(1, 520) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 778
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 778) = 778
GCD(1, 778) = ( 1 x 778 ) / 778
GCD(1, 778) = 778 / 778
GCD(1, 778) = 1
GCD of 280, 167, 520, 778 is 1
