1,19
Greatest Common Factor
We found the factors 15,28,48,19 . The biggest common factor number is the GCF number.
So the greatest common factor 15,28,48,19 is 1.
Lets's calculate LCM of 21,58,58,94
2 | 21, 58, 58, 94 |
29 | 21, 29, 29, 47 |
21, 1, 1, 47 |
∴ So the LCM of the given numbers is 2 x 29 x 21 x 1 x 1 x 47 = 57246
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/57246
Therefore, the GCF of Fractions 15/21,28/58,48/58,19/94 is 1/57246
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 21,58,58,94 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(21,58,58,94) = 1
common factors(in case of two or more numbers have common factors) = 116
GCF(21,58,58,94) x common factors =1 x 116 = 116
LCM(21,58,58,94) = ( 21 × 58 × 58 × 94 ) / 116
LCM(21,58,58,94) = 6640536 / 116
LCM(21,58,58,94) = 57246
