Greatest Common Factor
We found the factors 4,51,77,705 . The biggest common factor number is the GCF number.
So the greatest common factor 4,51,77,705 is 1.
Lets's calculate LCM of 87,25,326,924
2 | 87, 25, 326, 924 |
3 | 87, 25, 163, 462 |
29, 25, 163, 154 |
∴ So the LCM of the given numbers is 2 x 3 x 29 x 25 x 163 x 154 = 109193700
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/109193700
Therefore, the GCF of Fractions 4/87,51/25,77/326,705/924 is 1/109193700
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 87,25,326,924 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(87,25,326,924) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(87,25,326,924) x common factors =1 x 6 = 6
LCM(87,25,326,924) = ( 87 × 25 × 326 × 924 ) / 6
LCM(87,25,326,924) = 655162200 / 6
LCM(87,25,326,924) = 109193700
