Greatest Common Factor
We found the factors 154,789,908 . The biggest common factor number is the GCF number.
So the greatest common factor 154,789,908 is 1.
Lets's calculate LCM of 37,13,991
Given numbers has no common factors except 1. So, there LCM is their product i.e 476671
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/476671
Therefore, the GCF of Fractions 154/37,789/13,908/991 is 1/476671
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 37,13,991 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(37,13,991) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(37,13,991) x common factors =1 x 1 = 1
LCM(37,13,991) = ( 37 × 13 × 991 ) / 1
LCM(37,13,991) = 476671 / 1
LCM(37,13,991) = 476671
