Greatest Common Factor
We found the factors 28,45,880 . The biggest common factor number is the GCF number.
So the greatest common factor 28,45,880 is 1.
Lets's calculate LCM of 795,623,454
Given numbers has no common factors except 1. So, there LCM is their product i.e 224859390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/224859390
Therefore, the GCF of Fractions 28/795,45/623,880/454 is 1/224859390
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 795,623,454 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(795,623,454) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(795,623,454) x common factors =1 x 1 = 1
LCM(795,623,454) = ( 795 × 623 × 454 ) / 1
LCM(795,623,454) = 224859390 / 1
LCM(795,623,454) = 224859390
Here are some samples of GCF of Fractions calculations.
