We found the factors 455,980 . The biggest common factor number is the GCF number.
So the greatest common factor 455,980 is 35.
Lets's calculate LCM of 955,382
191 | 955, 382 |
5, 2 |
∴ So the LCM of the given numbers is 191 x 5 x 2 = 1910
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 35/1910
Therefore, the GCF of Fractions 455/955,980/382 is 35/1910
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 955,382 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(955,382) = 191
common factors(in case of two or more numbers have common factors) = 1
GCF(955,382) x common factors =191 x 1 = 191
LCM(955,382) = ( 955 × 382 ) / 191
LCM(955,382) = 364810 / 191
LCM(955,382) = 1910
