1,317
Greatest Common Factor
We found the factors 87,780,317 . The biggest common factor number is the GCF number.
So the greatest common factor 87,780,317 is 1.
Lets's calculate LCM of 98,81,610
2 | 98, 81, 610 |
49, 81, 305 |
∴ So the LCM of the given numbers is 2 x 49 x 81 x 305 = 2421090
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2421090
Therefore, the GCF of Fractions 87/98,780/81,317/610 is 1/2421090
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 98,81,610 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(98,81,610) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(98,81,610) x common factors =1 x 2 = 2
LCM(98,81,610) = ( 98 × 81 × 610 ) / 2
LCM(98,81,610) = 4842180 / 2
LCM(98,81,610) = 2421090
