:1,811
Greatest Common Factor
We found the factors 418,811 . The biggest common factor number is the GCF number.
So the greatest common factor 418,811 is 1.
Lets's calculate LCM of 647,670
Given numbers has no common factors except 1. So, there LCM is their product i.e 433490
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/433490
Therefore, the GCF of Fractions 418/647,811/670 is 1/433490
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 647,670 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(647,670) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(647,670) x common factors =1 x 1 = 1
LCM(647,670) = ( 647 × 670 ) / 1
LCM(647,670) = 433490 / 1
LCM(647,670) = 433490
