:1,2,7,11,14,22,77,154
Now, list down the factors of 699
:1,3,233,699
Greatest Common Factor
We found the factors 154,699 . The biggest common factor number is the GCF number.
So the greatest common factor 154,699 is 1.
Lets's calculate LCM of 811,838
Given numbers has no common factors except 1. So, there LCM is their product i.e 679618
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/679618
Therefore, the GCF of Fractions 154/811,699/838 is 1/679618
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 811,838 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(811,838) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(811,838) x common factors =1 x 1 = 1
LCM(811,838) = ( 811 × 838 ) / 1
LCM(811,838) = 679618 / 1
LCM(811,838) = 679618
