So the greatest common factor 2,6,6,28 is 2.
Lets's calculate LCM of 80,54,63,770
2 | 80, 54, 63, 770 |
3 | 40, 27, 63, 385 |
3 | 40, 9, 21, 385 |
5 | 40, 3, 7, 385 |
7 | 8, 3, 7, 77 |
8, 3, 1, 11 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 7 x 8 x 3 x 1 x 11 = 166320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/166320
Therefore, the GCF of Fractions 2/80,6/54,6/63,28/770 is 2/166320
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 80,54,63,770 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(80,54,63,770) = 1
common factors(in case of two or more numbers have common factors) = 1260
GCF(80,54,63,770) x common factors =1 x 1260 = 1260
LCM(80,54,63,770) = ( 80 × 54 × 63 × 770 ) / 1260
LCM(80,54,63,770) = 209563200 / 1260
LCM(80,54,63,770) = 166320
