So the greatest common factor 825,804 is 3.
Lets's calculate LCM of 970,194
2 | 970, 194 |
97 | 485, 97 |
5, 1 |
∴ So the LCM of the given numbers is 2 x 97 x 5 x 1 = 970
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/970
Therefore, the GCF of Fractions 825/970,804/194 is 3/970
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 970,194 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(970,194) = 194
common factors(in case of two or more numbers have common factors) = 1
GCF(970,194) x common factors =194 x 1 = 194
LCM(970,194) = ( 970 × 194 ) / 194
LCM(970,194) = 188180 / 194
LCM(970,194) = 970
