Greatest Common Factor
We found the factors 17,82,80,68 . The biggest common factor number is the GCF number.
So the greatest common factor 17,82,80,68 is 1.
Lets's calculate LCM of 62,22,30,99
2 | 62, 22, 30, 99 |
3 | 31, 11, 15, 99 |
11 | 31, 11, 5, 33 |
31, 1, 5, 3 |
∴ So the LCM of the given numbers is 2 x 3 x 11 x 31 x 1 x 5 x 3 = 30690
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/30690
Therefore, the GCF of Fractions 17/62,82/22,80/30,68/99 is 1/30690
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 62,22,30,99 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(62,22,30,99) = 1
common factors(in case of two or more numbers have common factors) = 132
GCF(62,22,30,99) x common factors =1 x 132 = 132
LCM(62,22,30,99) = ( 62 × 22 × 30 × 99 ) / 132
LCM(62,22,30,99) = 4051080 / 132
LCM(62,22,30,99) = 30690
