Greatest Common Factor
We found the factors 498,386 . The biggest common factor number is the GCF number.
So the greatest common factor 498,386 is 2.
Lets's calculate LCM of 778,240
2 | 778, 240 |
389, 120 |
∴ So the LCM of the given numbers is 2 x 389 x 120 = 93360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/93360
Therefore, the GCF of Fractions 498/778,386/240 is 2/93360
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 778,240 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(778,240) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(778,240) x common factors =2 x 1 = 2
LCM(778,240) = ( 778 × 240 ) / 2
LCM(778,240) = 186720 / 2
LCM(778,240) = 93360
