Greatest Common Factor
We found the factors 5708,2100 . The biggest common factor number is the GCF number.
So the greatest common factor 5708,2100 is 4.
Lets's calculate LCM of 861,644
7 | 861, 644 |
123, 92 |
∴ So the LCM of the given numbers is 7 x 123 x 92 = 79212
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/79212
Therefore, the GCF of Fractions 5708/861,2100/644 is 4/79212
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 861,644 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(861,644) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(861,644) x common factors =7 x 1 = 7
LCM(861,644) = ( 861 × 644 ) / 7
LCM(861,644) = 554484 / 7
LCM(861,644) = 79212
