Greatest Common Factor
We found the factors 630,908 . The biggest common factor number is the GCF number.
So the greatest common factor 630,908 is 2.
Lets's calculate LCM of 42,770
2 | 42, 770 |
7 | 21, 385 |
3, 55 |
∴ So the LCM of the given numbers is 2 x 7 x 3 x 55 = 2310
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2310
Therefore, the GCF of Fractions 630/42,908/770 is 2/2310
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 42,770 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,770) = 14
common factors(in case of two or more numbers have common factors) = 1
GCF(42,770) x common factors =14 x 1 = 14
LCM(42,770) = ( 42 × 770 ) / 14
LCM(42,770) = 32340 / 14
LCM(42,770) = 2310
