Greatest Common Factor
We found the factors 62,43,76,786 . The biggest common factor number is the GCF number.
So the greatest common factor 62,43,76,786 is 1.
Lets's calculate LCM of 45,18,77,21
3 | 45, 18, 77, 21 |
3 | 15, 6, 77, 7 |
7 | 5, 2, 77, 7 |
5, 2, 11, 1 |
∴ So the LCM of the given numbers is 3 x 3 x 7 x 5 x 2 x 11 x 1 = 6930
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6930
Therefore, the GCF of Fractions 62/45,43/18,76/77,786/21 is 1/6930
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 45,18,77,21 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,18,77,21) = 1
common factors(in case of two or more numbers have common factors) = 189
GCF(45,18,77,21) x common factors =1 x 189 = 189
LCM(45,18,77,21) = ( 45 × 18 × 77 × 21 ) / 189
LCM(45,18,77,21) = 1309770 / 189
LCM(45,18,77,21) = 6930
