:1,2,5,10,31,62,155,310
Greatest Common Factor
We found the factors 306,310 . The biggest common factor number is the GCF number.
So the greatest common factor 306,310 is 2.
Lets's calculate LCM of 540,280
2 | 540, 280 |
2 | 270, 140 |
5 | 135, 70 |
27, 14 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 27 x 14 = 7560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/7560
Therefore, the GCF of Fractions 306/540,310/280 is 2/7560
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 540,280 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(540,280) = 20
common factors(in case of two or more numbers have common factors) = 1
GCF(540,280) x common factors =20 x 1 = 20
LCM(540,280) = ( 540 × 280 ) / 20
LCM(540,280) = 151200 / 20
LCM(540,280) = 7560
