Greatest Common Factor
We found the factors 49,52,78,60 . The biggest common factor number is the GCF number.
So the greatest common factor 49,52,78,60 is 1.
Lets's calculate LCM of 21,45,27,185
3 | 21, 45, 27, 185 |
3 | 7, 15, 9, 185 |
5 | 7, 5, 3, 185 |
7, 1, 3, 37 |
∴ So the LCM of the given numbers is 3 x 3 x 5 x 7 x 1 x 3 x 37 = 34965
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/34965
Therefore, the GCF of Fractions 49/21,52/45,78/27,60/185 is 1/34965
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 21,45,27,185 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,45,27,185) = 1
common factors(in case of two or more numbers have common factors) = 135
GCF(21,45,27,185) x common factors =1 x 135 = 135
LCM(21,45,27,185) = ( 21 × 45 × 27 × 185 ) / 135
LCM(21,45,27,185) = 4720275 / 135
LCM(21,45,27,185) = 34965
