Now, list down the factors of 386
:1,2,193,386
Now, list down the factors of 115
:1,5,23,115
Greatest Common Factor
We found the factors 386,115 . The biggest common factor number is the GCF number.
So the greatest common factor 386,115 is 1.
Lets's calculate LCM of 761,553
Given numbers has no common factors except 1. So, there LCM is their product i.e 420833
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/420833
Therefore, the GCF of Fractions 386/761,115/553 is 1/420833
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 761,553 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(761,553) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(761,553) x common factors =1 x 1 = 1
LCM(761,553) = ( 761 × 553 ) / 1
LCM(761,553) = 420833 / 1
LCM(761,553) = 420833
