Greatest Common Divisior
We found the divisors of 278, 370, 987 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 278, 370, 987 is 1.
Therefore, GCD of numbers 278, 370, 987 is 1
Given Input Data is 278, 370, 987
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 278 is 2 x 139
Prime Factorization of 370 is 2 x 5 x 37
Prime Factorization of 987 is 3 x 7 x 47
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(278, 370) = 51430
GCD(278, 370) = ( 278 x 370 ) / 51430
GCD(278, 370) = 102860 / 51430
GCD(278, 370) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 987
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 987) = 1974
GCD(2, 987) = ( 2 x 987 ) / 1974
GCD(2, 987) = 1974 / 1974
GCD(2, 987) = 1
GCD of 278, 370, 987 is 1
