Greatest Common Factor
We found the factors 46,23,39,12 . The biggest common factor number is the GCF number.
So the greatest common factor 46,23,39,12 is 1.
Lets's calculate LCM of 42,93,93,71
3 | 42, 93, 93, 71 |
31 | 14, 31, 31, 71 |
14, 1, 1, 71 |
∴ So the LCM of the given numbers is 3 x 31 x 14 x 1 x 1 x 71 = 92442
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/92442
Therefore, the GCF of Fractions 46/42,23/93,39/93,12/71 is 1/92442
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 42,93,93,71 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,93,93,71) = 1
common factors(in case of two or more numbers have common factors) = 279
GCF(42,93,93,71) x common factors =1 x 279 = 279
LCM(42,93,93,71) = ( 42 × 93 × 93 × 71 ) / 279
LCM(42,93,93,71) = 25791318 / 279
LCM(42,93,93,71) = 92442
