We found the factors 839,3952 . The biggest common factor number is the GCF number.
So the greatest common factor 839,3952 is 1.
Lets's calculate LCM of 642,530
2 | 642, 530 |
321, 265 |
∴ So the LCM of the given numbers is 2 x 321 x 265 = 170130
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/170130
Therefore, the GCF of Fractions 839/642,3952/530 is 1/170130
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 642,530 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(642,530) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(642,530) x common factors =2 x 1 = 2
LCM(642,530) = ( 642 × 530 ) / 2
LCM(642,530) = 340260 / 2
LCM(642,530) = 170130
