Greatest Common Factor
We found the factors 88,12,47,81 . The biggest common factor number is the GCF number.
So the greatest common factor 88,12,47,81 is 1.
Lets's calculate LCM of 63,33,48,77
3 | 63, 33, 48, 77 |
7 | 21, 11, 16, 77 |
11 | 3, 11, 16, 11 |
3, 1, 16, 1 |
∴ So the LCM of the given numbers is 3 x 7 x 11 x 3 x 1 x 16 x 1 = 11088
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/11088
Therefore, the GCF of Fractions 88/63,12/33,47/48,81/77 is 1/11088
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 63,33,48,77 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(63,33,48,77) = 1
common factors(in case of two or more numbers have common factors) = 693
GCF(63,33,48,77) x common factors =1 x 693 = 693
LCM(63,33,48,77) = ( 63 × 33 × 48 × 77 ) / 693
LCM(63,33,48,77) = 7683984 / 693
LCM(63,33,48,77) = 11088
