We found the factors 120,973 . The biggest common factor number is the GCF number.
So the greatest common factor 120,973 is 1.
Lets's calculate LCM of 520,820
2 | 520, 820 |
2 | 260, 410 |
5 | 130, 205 |
26, 41 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 26 x 41 = 21320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/21320
Therefore, the GCF of Fractions 120/520,973/820 is 1/21320
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 520,820 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(520,820) = 20
common factors(in case of two or more numbers have common factors) = 1
GCF(520,820) x common factors =20 x 1 = 20
LCM(520,820) = ( 520 × 820 ) / 20
LCM(520,820) = 426400 / 20
LCM(520,820) = 21320
