Greatest Common Factor
We found the factors 13,14,63,42 . The biggest common factor number is the GCF number.
So the greatest common factor 13,14,63,42 is 1.
Lets's calculate LCM of 10,36,32,378
2 | 10, 36, 32, 378 |
2 | 5, 18, 16, 189 |
3 | 5, 9, 8, 189 |
3 | 5, 3, 8, 63 |
5, 1, 8, 21 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 3 x 5 x 1 x 8 x 21 = 30240
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/30240
Therefore, the GCF of Fractions 13/10,14/36,63/32,42/378 is 1/30240
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 10,36,32,378 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(10,36,32,378) = 2
common factors(in case of two or more numbers have common factors) = 72
GCF(10,36,32,378) x common factors =2 x 72 = 144
LCM(10,36,32,378) = ( 10 × 36 × 32 × 378 ) / 144
LCM(10,36,32,378) = 4354560 / 144
LCM(10,36,32,378) = 30240
