3 | 351, 816 |
117, 272 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 351
:1,3,9,13,27,39,117,351
Now, list down the factors of 816
:1,2,3,4,6,8,12,16,17,24,34,48,51,68,102,136,204,272,408,816
Greatest Common Factor
We found the factors 351,816 . The biggest common factor number is the GCF number.
So the greatest common factor 351,816 is 3.
Lets's calculate LCM of 862,851
Given numbers has no common factors except 1. So, there LCM is their product i.e 733562
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/733562
Therefore, the GCF of Fractions 351/862,816/851 is 3/733562
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 862,851 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(862,851) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(862,851) x common factors =1 x 1 = 1
LCM(862,851) = ( 862 × 851 ) / 1
LCM(862,851) = 733562 / 1
LCM(862,851) = 733562
