Now, list down the factors of 7150
:1,2,5,10,11,13,22,25,26,50,55,65,110,130,143,275,286,325,550,650,715,1430,3575,7150
Greatest Common Factor
We found the factors 1285,7150 . The biggest common factor number is the GCF number.
So the greatest common factor 1285,7150 is 5.
Lets's calculate LCM of 842,2154
2 | 842, 2154 |
421, 1077 |
∴ So the LCM of the given numbers is 2 x 421 x 1077 = 906834
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/906834
Therefore, the GCF of Fractions 1285/842,7150/2154 is 5/906834
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 842,2154 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(842,2154) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(842,2154) x common factors =2 x 1 = 2
LCM(842,2154) = ( 842 × 2154 ) / 2
LCM(842,2154) = 1813668 / 2
LCM(842,2154) = 906834
