Greatest Common Factor
We found the factors 92,77,275 . The biggest common factor number is the GCF number.
So the greatest common factor 92,77,275 is 1.
Lets's calculate LCM of 19,20,28
2 | 19, 20, 28 |
2 | 19, 10, 14 |
19, 5, 7 |
∴ So the LCM of the given numbers is 2 x 2 x 19 x 5 x 7 = 2660
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2660
Therefore, the GCF of Fractions 92/19,77/20,275/28 is 1/2660
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 19,20,28 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,20,28) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(19,20,28) x common factors =1 x 4 = 4
LCM(19,20,28) = ( 19 × 20 × 28 ) / 4
LCM(19,20,28) = 10640 / 4
LCM(19,20,28) = 2660
