Now, list down the factors of 781
:1,11,71,781
Now, list down the factors of 346
:1,2,173,346
Greatest Common Factor
We found the factors 781,346 . The biggest common factor number is the GCF number.
So the greatest common factor 781,346 is 1.
Lets's calculate LCM of 720,247
Given numbers has no common factors except 1. So, there LCM is their product i.e 177840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/177840
Therefore, the GCF of Fractions 781/720,346/247 is 1/177840
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 720,247 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(720,247) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(720,247) x common factors =1 x 1 = 1
LCM(720,247) = ( 720 × 247 ) / 1
LCM(720,247) = 177840 / 1
LCM(720,247) = 177840
