Greatest Common Factor
We found the factors 97,46,39,109 . The biggest common factor number is the GCF number.
So the greatest common factor 97,46,39,109 is 1.
Lets's calculate LCM of 14,90,92,89
2 | 14, 90, 92, 89 |
7, 45, 46, 89 |
∴ So the LCM of the given numbers is 2 x 7 x 45 x 46 x 89 = 2579220
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2579220
Therefore, the GCF of Fractions 97/14,46/90,39/92,109/89 is 1/2579220
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 14,90,92,89 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(14,90,92,89) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(14,90,92,89) x common factors =1 x 4 = 4
LCM(14,90,92,89) = ( 14 × 90 × 92 × 89 ) / 4
LCM(14,90,92,89) = 10316880 / 4
LCM(14,90,92,89) = 2579220
