1,2,4,7,14,28
Greatest Common Factor
We found the factors 92,31,50,28 . The biggest common factor number is the GCF number.
So the greatest common factor 92,31,50,28 is 1.
Lets's calculate LCM of 83,21,15,55
3 | 83, 21, 15, 55 |
5 | 83, 7, 5, 55 |
83, 7, 1, 11 |
∴ So the LCM of the given numbers is 3 x 5 x 83 x 7 x 1 x 11 = 95865
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/95865
Therefore, the GCF of Fractions 92/83,31/21,50/15,28/55 is 1/95865
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 83,21,15,55 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(83,21,15,55) = 1
common factors(in case of two or more numbers have common factors) = 15
GCF(83,21,15,55) x common factors =1 x 15 = 15
LCM(83,21,15,55) = ( 83 × 21 × 15 × 55 ) / 15
LCM(83,21,15,55) = 1437975 / 15
LCM(83,21,15,55) = 95865
