Greatest Common Factor
We found the factors 45,19,45,479 . The biggest common factor number is the GCF number.
So the greatest common factor 45,19,45,479 is 1.
Lets's calculate LCM of 40,68,78,60
2 | 40, 68, 78, 60 |
2 | 20, 34, 39, 30 |
3 | 10, 17, 39, 15 |
5 | 10, 17, 13, 5 |
2, 17, 13, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 2 x 17 x 13 x 1 = 26520
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/26520
Therefore, the GCF of Fractions 45/40,19/68,45/78,479/60 is 1/26520
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 40,68,78,60 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,68,78,60) = 2
common factors(in case of two or more numbers have common factors) = 240
GCF(40,68,78,60) x common factors =2 x 240 = 480
LCM(40,68,78,60) = ( 40 × 68 × 78 × 60 ) / 480
LCM(40,68,78,60) = 12729600 / 480
LCM(40,68,78,60) = 26520
