Lets's calculate LCM of 875,574
7 | 875, 574 |
125, 82 |
∴ So the LCM of the given numbers is 7 x 125 x 82 = 71750
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/71750
Therefore, the GCF of Fractions 790/875,278/574 is 2/71750
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 875,574 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(875,574) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(875,574) x common factors =7 x 1 = 7
LCM(875,574) = ( 875 × 574 ) / 7
LCM(875,574) = 502250 / 7
LCM(875,574) = 71750
