:1,811
Greatest Common Factor
We found the factors 164,811 . The biggest common factor number is the GCF number.
So the greatest common factor 164,811 is 1.
Lets's calculate LCM of 336,140
2 | 336, 140 |
2 | 168, 70 |
7 | 84, 35 |
12, 5 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 12 x 5 = 1680
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1680
Therefore, the GCF of Fractions 164/336,811/140 is 1/1680
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 336,140 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(336,140) = 28
common factors(in case of two or more numbers have common factors) = 1
GCF(336,140) x common factors =28 x 1 = 28
LCM(336,140) = ( 336 × 140 ) / 28
LCM(336,140) = 47040 / 28
LCM(336,140) = 1680
