So the greatest common factor 70,90,53,13 is 1.
Lets's calculate LCM of 19,69,84,294
2 | 19, 69, 84, 294 |
3 | 19, 69, 42, 147 |
7 | 19, 23, 14, 49 |
19, 23, 2, 7 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 19 x 23 x 2 x 7 = 256956
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/256956
Therefore, the GCF of Fractions 70/19,90/69,53/84,13/294 is 1/256956
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 19,69,84,294 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,69,84,294) = 1
common factors(in case of two or more numbers have common factors) = 126
GCF(19,69,84,294) x common factors =1 x 126 = 126
LCM(19,69,84,294) = ( 19 × 69 × 84 × 294 ) / 126
LCM(19,69,84,294) = 32376456 / 126
LCM(19,69,84,294) = 256956
