:1,2,5,10,47,94,235,470
Greatest Common Factor
We found the factors 765,470 . The biggest common factor number is the GCF number.
So the greatest common factor 765,470 is 5.
Lets's calculate LCM of 40,852
2 | 40, 852 |
2 | 20, 426 |
10, 213 |
∴ So the LCM of the given numbers is 2 x 2 x 10 x 213 = 8520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/8520
Therefore, the GCF of Fractions 765/40,470/852 is 5/8520
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 40,852 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,852) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(40,852) x common factors =4 x 1 = 4
LCM(40,852) = ( 40 × 852 ) / 4
LCM(40,852) = 34080 / 4
LCM(40,852) = 8520
