Greatest Common Factor
We found the factors 782,867,634 . The biggest common factor number is the GCF number.
So the greatest common factor 782,867,634 is 1.
Lets's calculate LCM of 42,33,71
3 | 42, 33, 71 |
14, 11, 71 |
∴ So the LCM of the given numbers is 3 x 14 x 11 x 71 = 32802
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/32802
Therefore, the GCF of Fractions 782/42,867/33,634/71 is 1/32802
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 42,33,71 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,33,71) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(42,33,71) x common factors =1 x 3 = 3
LCM(42,33,71) = ( 42 × 33 × 71 ) / 3
LCM(42,33,71) = 98406 / 3
LCM(42,33,71) = 32802
