Greatest Common Factor
We found the factors 345,9280 . The biggest common factor number is the GCF number.
So the greatest common factor 345,9280 is 5.
Lets's calculate LCM of 977,985
Given numbers has no common factors except 1. So, there LCM is their product i.e 962345
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/962345
Therefore, the GCF of Fractions 345/977,9280/985 is 5/962345
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 977,985 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(977,985) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(977,985) x common factors =1 x 1 = 1
LCM(977,985) = ( 977 × 985 ) / 1
LCM(977,985) = 962345 / 1
LCM(977,985) = 962345
Here are some samples of GCF of Fractions calculations.
