Greatest Common Factor
We found the factors 96,51,42 . The biggest common factor number is the GCF number.
So the greatest common factor 96,51,42 is 3.
Lets's calculate LCM of 63,66,74
2 | 63, 66, 74 |
3 | 63, 33, 37 |
21, 11, 37 |
∴ So the LCM of the given numbers is 2 x 3 x 21 x 11 x 37 = 51282
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/51282
Therefore, the GCF of Fractions 96/63,51/66,42/74 is 3/51282
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 63,66,74 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,66,74) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(63,66,74) x common factors =1 x 6 = 6
LCM(63,66,74) = ( 63 × 66 × 74 ) / 6
LCM(63,66,74) = 307692 / 6
LCM(63,66,74) = 51282
