Lets's calculate LCM of 852,980
2 | 852, 980 |
2 | 426, 490 |
213, 245 |
∴ So the LCM of the given numbers is 2 x 2 x 213 x 245 = 208740
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/208740
Therefore, the GCF of Fractions 462/852,8121/980 is 3/208740
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 852,980 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(852,980) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(852,980) x common factors =4 x 1 = 4
LCM(852,980) = ( 852 × 980 ) / 4
LCM(852,980) = 834960 / 4
LCM(852,980) = 208740
