Greatest Common Factor
We found the factors 47,27,35,415 . The biggest common factor number is the GCF number.
So the greatest common factor 47,27,35,415 is 1.
Lets's calculate LCM of 90,98,78,60
2 | 90, 98, 78, 60 |
3 | 45, 49, 39, 30 |
5 | 15, 49, 13, 10 |
3, 49, 13, 2 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 3 x 49 x 13 x 2 = 114660
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/114660
Therefore, the GCF of Fractions 47/90,27/98,35/78,415/60 is 1/114660
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 90,98,78,60 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(90,98,78,60) = 2
common factors(in case of two or more numbers have common factors) = 180
GCF(90,98,78,60) x common factors =2 x 180 = 360
LCM(90,98,78,60) = ( 90 × 98 × 78 × 60 ) / 360
LCM(90,98,78,60) = 41277600 / 360
LCM(90,98,78,60) = 114660
