1,2,7,14,367,734,2569,5138
Greatest Common Factor
We found the factors 469,5138 . The biggest common factor number is the GCF number.
So the greatest common factor 469,5138 is 7.
Lets's calculate LCM of 172,870
2 | 172, 870 |
86, 435 |
∴ So the LCM of the given numbers is 2 x 86 x 435 = 74820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/74820
Therefore, the GCF of Fractions 469/172,5138/870 is 7/74820
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 172,870 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(172,870) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(172,870) x common factors =2 x 1 = 2
LCM(172,870) = ( 172 × 870 ) / 2
LCM(172,870) = 149640 / 2
LCM(172,870) = 74820
