So the greatest common factor 852,248 is 4.
Lets's calculate LCM of 172,742
2 | 172, 742 |
86, 371 |
∴ So the LCM of the given numbers is 2 x 86 x 371 = 63812
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/63812
Therefore, the GCF of Fractions 852/172,248/742 is 4/63812
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 172,742 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(172,742) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(172,742) x common factors =2 x 1 = 2
LCM(172,742) = ( 172 × 742 ) / 2
LCM(172,742) = 127624 / 2
LCM(172,742) = 63812
