Greatest Common Factor
We found the factors 385,769 . The biggest common factor number is the GCF number.
So the greatest common factor 385,769 is 1.
Lets's calculate LCM of 670,423
Given numbers has no common factors except 1. So, there LCM is their product i.e 283410
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/283410
Therefore, the GCF of Fractions 385/670,769/423 is 1/283410
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 670,423 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(670,423) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(670,423) x common factors =1 x 1 = 1
LCM(670,423) = ( 670 × 423 ) / 1
LCM(670,423) = 283410 / 1
LCM(670,423) = 283410
