Greatest Common Factor
We found the factors 45,66,124 . The biggest common factor number is the GCF number.
So the greatest common factor 45,66,124 is 1.
Lets's calculate LCM of 521,579,833
Given numbers has no common factors except 1. So, there LCM is their product i.e 251281947
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/251281947
Therefore, the GCF of Fractions 45/521,66/579,124/833 is 1/251281947
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 521,579,833 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(521,579,833) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(521,579,833) x common factors =1 x 1 = 1
LCM(521,579,833) = ( 521 × 579 × 833 ) / 1
LCM(521,579,833) = 251281947 / 1
LCM(521,579,833) = 251281947
