Lets's calculate GCF of 896,889
7 | 896, 889 |
128, 127 |
∴ So the GCF of the given numbers is 7 = 7
Now, list down the factors of 896
:1,2,4,7,8,14,16,28,32,56,64,112,128,224,448,896
Now, list down the factors of 889
:1,7,127,889
Greatest Common Factor
We found the factors 896,889 . The biggest common factor number is the GCF number.
So the greatest common factor 896,889 is 7.
Lets's calculate LCM of 28,154
2 | 28, 154 |
7 | 14, 77 |
2, 11 |
∴ So the LCM of the given numbers is 2 x 7 x 2 x 11 = 308
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/308
Therefore, the GCF of Fractions 896/28,889/154 is 7/308
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 28,154 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,154) = 14
common factors(in case of two or more numbers have common factors) = 1
GCF(28,154) x common factors =14 x 1 = 14
LCM(28,154) = ( 28 × 154 ) / 14
LCM(28,154) = 4312 / 14
LCM(28,154) = 308
