Greatest Common Factor
We found the factors 44,13,54,15 . The biggest common factor number is the GCF number.
So the greatest common factor 44,13,54,15 is 1.
Lets's calculate LCM of 17,21,42,936
2 | 17, 21, 42, 936 |
3 | 17, 21, 21, 468 |
7 | 17, 7, 7, 156 |
17, 1, 1, 156 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 17 x 1 x 1 x 156 = 111384
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/111384
Therefore, the GCF of Fractions 44/17,13/21,54/42,15/936 is 1/111384
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 17,21,42,936 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,21,42,936) = 1
common factors(in case of two or more numbers have common factors) = 126
GCF(17,21,42,936) x common factors =1 x 126 = 126
LCM(17,21,42,936) = ( 17 × 21 × 42 × 936 ) / 126
LCM(17,21,42,936) = 14034384 / 126
LCM(17,21,42,936) = 111384
