We found the factors 127,4030 . The biggest common factor number is the GCF number.
So the greatest common factor 127,4030 is 1.
Lets's calculate LCM of 390,520
2 | 390, 520 |
5 | 195, 260 |
13 | 39, 52 |
3, 4 |
∴ So the LCM of the given numbers is 2 x 5 x 13 x 3 x 4 = 1560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1560
Therefore, the GCF of Fractions 127/390,4030/520 is 1/1560
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 390,520 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(390,520) = 130
common factors(in case of two or more numbers have common factors) = 1
GCF(390,520) x common factors =130 x 1 = 130
LCM(390,520) = ( 390 × 520 ) / 130
LCM(390,520) = 202800 / 130
LCM(390,520) = 1560
