Greatest Common Factor
We found the factors 6405,8784 . The biggest common factor number is the GCF number.
So the greatest common factor 6405,8784 is 183.
Lets's calculate LCM of 688,921
Given numbers has no common factors except 1. So, there LCM is their product i.e 633648
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 183/633648
Therefore, the GCF of Fractions 6405/688,8784/921 is 183/633648
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 688,921 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(688,921) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(688,921) x common factors =1 x 1 = 1
LCM(688,921) = ( 688 × 921 ) / 1
LCM(688,921) = 633648 / 1
LCM(688,921) = 633648
