Greatest Common Factor
We found the factors 44,77,54,90 . The biggest common factor number is the GCF number.
So the greatest common factor 44,77,54,90 is 1.
Lets's calculate LCM of 26,52,64,70
2 | 26, 52, 64, 70 |
2 | 13, 26, 32, 35 |
13 | 13, 13, 16, 35 |
1, 1, 16, 35 |
∴ So the LCM of the given numbers is 2 x 2 x 13 x 1 x 1 x 16 x 35 = 29120
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/29120
Therefore, the GCF of Fractions 44/26,77/52,54/64,90/70 is 1/29120
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 26,52,64,70 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(26,52,64,70) = 2
common factors(in case of two or more numbers have common factors) = 104
GCF(26,52,64,70) x common factors =2 x 104 = 208
LCM(26,52,64,70) = ( 26 × 52 × 64 × 70 ) / 208
LCM(26,52,64,70) = 6056960 / 208
LCM(26,52,64,70) = 29120
