So the greatest common factor 42,809,286 is 1.
Lets's calculate LCM of 63,42,881
3 | 63, 42, 881 |
7 | 21, 14, 881 |
3, 2, 881 |
∴ So the LCM of the given numbers is 3 x 7 x 3 x 2 x 881 = 111006
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/111006
Therefore, the GCF of Fractions 42/63,809/42,286/881 is 1/111006
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 63,42,881 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,42,881) = 1
common factors(in case of two or more numbers have common factors) = 21
GCF(63,42,881) x common factors =1 x 21 = 21
LCM(63,42,881) = ( 63 × 42 × 881 ) / 21
LCM(63,42,881) = 2331126 / 21
LCM(63,42,881) = 111006
